Feature Showcase App Guide - SAP-samples/abap-platform-fiori-feature-showcase GitHub Wiki
Tip
A newer version of the Guide is also available, separated into 6 files. Please refer to README.
Tips on how to use this Guide:
When you see a feature that you would like to implement, copy or take note of the search term (e.g., #SearchTermExample) and perform a search here. You will be presented with
- a short description of the feature,
- code snippets and where to find them in the source code,
- and in some cases, a link to the official RAP documentation for more information.
💡 Take note that the links will always lead you to the RAP documentation for the latest release! You have to take into account the version of the system you have.
Alternatively, you can search for an annotation here, get the search term, and use it to locate the UI feature in the app. If the annotation cannot be found, it could simply mean that it is not showcased in the current release.
Search term: #IANATimezone
Warning
Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.
With the annotation @Semantics.timeZone you can convert a timezone to one specified according to the IANA standard. You are also able to assign this converted timezone to a timestamp (which has to be in the UTC format) so that the time will be interpreted in this timezone. The annotation to use is @Semantics.timeZoneReference.
The conversion of the timezone is happening at the backend, while the timestamp conversion is done by the UI.
This feature is also available for use with action/function parameters.
In the following example, changing the SAPTimezone field will also change IANATimezone and IANATimestamp, which are both shown in IANA standard and changing Timestamp will change IANATimestamp automatically. This is achieved via side effect.

Search term: #ValueHelps, #DependentFilter
The implementation of a value help in CDS enables the end user to choose values from a predefined list for input fields on a user interface.
The additional binding defines a second condition for the value help on the same target value help provider entity for filtering the value help result list and/or returning values from the selected value help record. The additional binding can be defined for an additional element or parameter. Depending on the value provided in usage, the additional binding works as a filter, result or filter and result condition
Usage: #Result: The referenced element or parameter in localElement or localParameter is filled with the value provided by the value help. When creating an instance, you can fill various fields with this option.

Warning
Only shown in the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.
To mark a value help as an input validator, one can use the keyword useForValidation: true in the annotation @Consumption.valueHelpDefinition. It can be annotated at a field, a CDS parameter or an action parameter.
It is good practice to use the keyword qualifier for every value help, even if the field only has one. If you have defined more than one value help at a field, useForValidation might not work correctly if you have forgotten to use qualifiers, as UI would not be able to determine which value help is to be used for validation.
This keyword does not work for collective value helps.
💡 If you have a draft-enabled app, using this annotation prevents an invalid value from being saved to draft. A refresh of the page will clear the user input.
💡 Another alternative to this annotation would be to use a drop down list with @ObjectModel : { resultSet.sizeCategory: #XS }, if there are not too many available choices.

Search term: #StaticFeatureCtrl
Each field can have specific access restrictions, defined in the behaviour definition. If the access restriction is always the same for each instance, you can use static feature control. Some examples/possible combinations are described here:
Note
Source: Behaviour Definition /DMO/FSA_R_RootTP
define behavior for /DMO/FSA_R_RootTP alias Root
...
{
field ( readonly, numbering : managed ) ID;
field ( mandatory ) Email;
field ( mandatory : create, readonly : update ) StringProperty;
}
There are 2 different types of readonly:
field ( readonly, numbering : managed ) ID; means that the field ID is a key that will be assigned a value by the framework (numering:managed) and must not be created or updated by the user at all (readonly). The annotation in $metadata is <Annotation Term="SAP__core.Computed"/>.
field ( mandatory : create, readonly : update ) StringProperty; means that the field StringProperty is only mandatory during create, but after that it will be read only. The annotation for the readonly in $metadata is <Annotation Term="SAP__core.Immutable"/>.
field ( mandatory ) Email; means that the user must provide a value for the field Email. The annotation in $metadata is <Annotation Term="SAP__common.FieldControl" EnumMember="SAP__common.FieldControlType/Mandatory"/>.

Each field can have specific access restrictions, defined in the behaviour definition and behaviour implementation. If the access restriction depends on a certain condition, you can implement the feature control dynamically.

ENDMETHOD.
In this simple example, the field TimesChildCreated is dynamically assigned the restriction read-only.
The annotation in $metadata is <Annotation Term="SAP__common.FieldControl" Path="__FieldControl/TimesChildCreated"/>.
For dynamic control of operations and actions, the option (features: instance) must be added to the operation or action.

An action that is defined via Datafield ForAction is not tied to a specific data value. Therefore it is possible to assign the annotation to any arbitary element. Whether the action button is to be in the list report or object page, line item or section, this largely depends on the respective UI annotation you use. More examples are listed below in this guide, if you search for action.
The keyword to use for this is type: #FOR_ACTION in @UI.lineItem, @UI.fieldGroup, etc.

An action that is tied to a data value, which would be rendered as a hyperlink. Therefore it is crucial to specify the annotation at the desired element which has the data value. Whether the action button is to be in the list report or object page, line item or section, this largely depends on the respective UI annotation you use.
The keyword to use for this is type: #WITH_ACTION in @UI.lineItem, @UI.fieldGroup, @UI.identification.

It is possible to define mandatory parameters for action/functions but to do this, you would need a behaviour definition for the abstract entity. This is typically a deep parameter with a hierarchy structure but instead of a true hierarchy with associations, we define the abstract entity as a flat structure.
In this example, the field sap_timezone should be a mandatory parameter and will be marked with a red asterisk (*) . The keyword to use is mandatory:execute, to be marked at the field in the behaviour definition.

With a default values function you can default the input parameters for actions, functions, as well as create and create-by-association operations, similar to the annotation @UI.defaultValue (see Default Value for action parameter). The difference here is, with default values function you can specify the values using more complicated coding.
The general rules are:
- Function name must begin with
GetDefaultsFor - Function name must be unique within the current BDEF
- In certain cases, external names can be given
- Key word is
{default function GetDefaultsForxxx;}behind the respective operation
The importing parameter and the return type of the function need not be specified, as they will be derived by the framework from the respective actions/operations. If you have a projection layer, it is necessary to expose the default values function too in the projection BDEF.
In this example, the property StringProperty, which is a mandatory input for create, will be prefilled with the value Default Value for Root Create.
Further rules:
- Function name after the keyword
default functionis optional. When specified it must beGetDefaultsForCreate - External name is not possible

A quick view is a pop up that shows more information, when you click on an entry in a column or an object page. Typically, it is used in combination with one-to-one or zero-to-one associations. By clicking on the link, more information about the associated entity can be displayed.
To enable a quick view facet, the association entity needs to be annotated with @UI.facet with type: #QUICK_VIEW. For a better looking header of the quick view, the association entity gets typically annotated with @UI.headerInfo. Additionally, the key value can be replaced with another text property using @ObjectModel.text.element, so that the column is readable.

When your associated entity (QuickView entity) has a key that is non-UUID, a referential constraint for the association does not get generated automatically. To do so, a property needs to act as a null value indicator for the QuickView property, similar to a value control property, using the annotation @Semantics.nullValueIndicatorFor.

Important
UI Adaptation is only possible with deployed apps. Therefore some features of this annotation cannot be showcased in the Feature Showcase App app preview, unless stated otherwise.
UI adaptation is a feature of SAPUI5 flexibility that allows key users without technical knowledge to easily make UI changes for all users of an app, end users to personalize controls, and developers to extend the UIs of SAPUI5 applications. For more information, see SAPUI5 Flexibility: Adapting UIs Made Easy.
But there are some scenarios where you do not want to allow this, that a specific property or entity should only adher to the metadata or annotations. It is possible to do this, by using the annotation @UI.adaptationHidden: true.
As a result, the property Description cannot
- be removed or added in, in the object page
- have its label/description be edited
- have its position on the object page be changed via drag-and-drop
In addition to the above, the property Description cannot
- be added in as a list report filter
Note

Search term: #SimpleType
Warning
Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release.
Simple types allow the definition of user-defined scalar types together with (arbitrary) domain-specific metadata via CDS annotations.
Simpler put, you can create user-defined data types in ABAP CDS, which work similarly to Data Elements in DDIC. The advantages of CDS simple types are:
- you can type them to build-in data types like
abap.int4, DDIC data elements, or even other CDS simple types - you can use a fixed list of CDS annotations to enrich the metadata of these data types, including but not limited to:
EndUserText,Semantics, and others
Tip
To get the full list of allowed annotations in simple type, simply use Code Completion in ADT with Ctrl + Space after typing @
These data types can be used in CDS views by view parameters directly, or by properties via casting, and also directly by parameters in abstract entities. You can also use them in your ABAP code, especially when you are developing the behaviour implementation of RAP business objects.
Warning
Do not use CDS Simple Type with enumeration as it is not supported in RAP. CDS Simple Type is not supported in classic DDIC like tables and structures

To see columns in your table, you would first have to define them with the annotation @UI.lineItem at the property, either in the CDS view or in a metadata extension. The most basic setting you can use would be:
- the order of the column in the table and
- changing the column label, if you do not want to use the label from underlying views.
In the example below, StringProperty would be the second column in the table (the numbering used here is 10, 20, etc. You could also start with 1, 2, etc. ), defined using position. label would be the column label/heading.
importance denotes the importance of the property. With #HIGH, this means that the property will always be shown even if the table is rendered on a small display.

For a deep copy of an instance, the RAP framework does not provide a copy action out of the box, unlike create/edit/delete. However you can define a factory action in the BDEF that copies an instance, and by using the keyword isCopyAction: true, the action button will be rendered in UI harmoniously with Create/Delete. When no label is provided, it is automatically set to 'Copy'.
The cardinality of a factory action is always [1], that means, only one instance can be copied at a time.
When used in conjunction with inline: true to render the Copy button at individual line items, a label must be provided by you.

Search term: #ContactInHeader, #ContactInLineItem, #Contact
To have a data field which shows a contact with a contact quick view, the contact quick view needs to be implemented first. An example would be:
Note

// Search Term #Contact
define view entity /DMO/FSA_I_Contact
{
@ObjectModel.text.element: ['Name'] // Search Term #DisplayTextAndID

street as Street,
@Semantics.address.city: true
city as City,
@Semantics.address.zipCode: true
postcode as Postcode,
@Semantics.address.label: true
address_label as AddressLabel
}
To show the contact card in the table you need to annotate the contact property with @UI.lineItem or if in a facet, with @UI.fieldGroup.

A quick view is a pop up that shows more information, when you click on an entry in a column or an object page. Typically, it is used in combination with one-to-one or zero-to-one associations. By clicking on the link, more information about the associated entity can be displayed.
To set up an entity as QuickView, follow the steps here: Setting up QuickView
To show the QuickView in a table, just use annotation @UI.lineItem to add the property, with has referential constraint defined, into the table.

You can enable your RAP application for maintaining large objects (LOBs). By doing so, you provide end users the option to incorporate external binary files or text files when editing entity instances. First the appropriate fields should be added into the database table and the CDS view, and also the annotations @Semantics.largeObject and @Semantics.mimeType. To show it in a table, you will need annotation @UI.lineItem. Lastly, you should also update the mapping and the draft table in your behaviour definition.

Search term: #CollectiveValueHelp
For SAP GUI-based applications it is possible to define a collective search help that combines several elementary search helps. You can choose one of several alternative search paths and retrieve input values from multiple sources/tables in a single dialog. In Fiori UI this is also possible via a collective value help using an abstract entity comprising a list of assigned elementary search helps and potential mappings of the bound field names.
The collective value help shall be annotated with @ObjectModel.collectiveValueHelp.for.element pointing to the field, for which the collective value help is defined. The field referenced by @ObjectModel.collectiveValueHelp.for.element shall be assigned at least a single elementary value help using annotation @Consumption.valueHelpDefinition.
Only the following keywords can be used for a collective value help: entity.name, entity.element, additionalBinding.localElement, additionalBinding.element and qualifier.
Note

Side Effects annotations specify to the UI, which targets to be refreshed in order to show updated values that arises from field changes, actions, or determine actions. Side effects are defined in the behaviour definition. There are a variety of ways to annotate side effects by combining the triggers and the affected components, and a few examples are shown in the app:
Warning
If you use projection, remember to add the following to your projection behaviour definition.
projection...
use side effects;
define behavior for ProjectionView {
}
Fields from same level entity
When the user changes the value of IntegerValue, the determination setIntegerValue is called and modifies the values of ProgressIntegerValue and RadialIntegerValue. In order for these 2 fields to show the updated values without a refresh, side effects is required to request UI to reload these 2 fields.

Fields from associated entity
It is also possible to define as target, a field from an assoicated entity. When the field ChildPieces in Child entity is modified, this will trigger the determination calculateTotalPieces to total up the pieces of all child instances. Side effects will trigger the refresh of field TotalPieces from the Root entity to show the calculated total every time user enters a value at the child instance.

When an instance of an associated entity is deleted, a field should be updated. While there is no dedicated syntax to cater for this use case, this can be achieved with a workaround by defining a determination that is always called by a determine action, with side effect defined for the determine action.

The following micro charts are supported: Area, Bullet, Radial, Column, Line, Harvey, Stacked bar and Comparison. Micro charts can only be displayed in the header.
A micro chart is defined with the @UI.chart annotation, which then is the target of a ReferenceFacet in the @UI.facet of purpose: #HEADER. The title of the facet is the attribute title of the annotation and the subtitle is description. If the property of the data point is a property with unit of measure, the unit will be displayed in the footer. The attribute measures of the chart has to be a data point.
The @UI.dataPoint supports generally the attributes criticality and criticalityCalculation, but the support varies between the micro chart types. If the value of the data point is annotated with a unit of measure, the unit will be shown as the footer of the micro chart facet.
In the following examples, all used attributes are mandatory.
Search term: #AreaMicroChart
The area micro chart is a trend chart, which provides information for the actual and target value for a specified dimension. The displayed values at the bottom of the chart are the boundary values of the dimension. The values above the chart are the boundary values of the measure attribute.

For a deep copy of an instance, the RAP framework does not provide a copy action out of the box, unlike create/edit/delete. However you can define a factory action in the BDEF that copies an instance, and by using the keyword isCopyAction: true, the action button will be rendered in UI harmoniously with Edit/Delete.
The cardinality of a factory action is always [1], that means, only one instance can be copied at a time.

You can enable your RAP application for maintaining large objects (LOBs). By doing so, you provide end users the option to incorporate external binary files or text files when editing entity instances. First the appropriate fields should be added into the database table and the CDS view, and also the annotations @Semantics.largeObject and @Semantics.mimeType. To show it in a standard or header facet, you will need annotation @UI.facet. Lastly, you should also update the mapping and the draft table in your behaviour definition.

ABAP CDS allows for the structuring of data in hierarchies. For RAP, it is possible to display this CDS Hierarchy as a readonly treeview in the SAP Fiori UI, either as a list report which has a different implementation (an example can be found in ABAP RESTful Application Programming Model: Implementing Treeviews) or in the object page, which will be described hereafter.
The example implemented here represents a file folder system. Each folder has a parent folder, which is itself a 'normal' folder, and the topmost/root folder does not have a parent. Each folder is named with a combination of colour and number, and the name is used to sort the hiearchy. The root entity will serve as a 'directory' so that each instance has its own hierarchy which can be displayed in the object page.
To implement this you would need the following artifacts:
The root_id contains the id of the directory, in this case the root instance. parent_folder contains the folder_id of the parent.
Note
Source: Database table /DMO/FSA_FLDR_A
define table /dmo/fsa_fldr_a {
key client : abap.clnt not null;
key root_id : sysuuid_x16 not null;
key folder_id : sysuuid_c22 not null;
parent_folder : sysuuid_c22;
folder_name : abap.char(1024);
folder_size : abap.dec(10,2);
}
It serves as the source for the hierarchy, has a self-association and an association to the root entity, the directory. Annotations depicting how the treeview is shown in UI is also declared here. The most important annotation, @OData.hierarchy.recursiveHierarchy is required to specify the hierarchy.

The source of the hierarchy is /DMO/FSA_I_Folder. The parent of a node is defined via association _ParentFolder, which is a self-association. The hierarchy is filtered with parameter P_Directory, which is the ID of the root instance so that the correct hierarchy is shown in the object page of the instance. The topmost node is the one with an initial ParentFolder and the hierarchy is sorted by FolderName.
Note

Only available with the latest SAP BTP or SAP S/4HANA Cloud, public edition release and for SAP S/4HANA, on-premise edition or SAP S/4HANA Cloud, private edition, from release 2023 onwards.
Action overload means to add an action bound to another entity, to the object page list table of a child entity. The action is defined in the behaviour definition, and the UI annotation to add the action is defined in the other entity's CDS view or metadata extension.
The example given here, is an action button displayed at the Child entity table in section Child Entity (1..n)(#OPTable), that calls a Root action to create a new Child instance.

Search term: #ChartSection
As an alternative to micro charts in the header, charts are also possible as sections. However the implementation is more complex. As aggregation is not yet available for V4 services, which this app is based on, the following shows only an example of how a chart should be annotated.
First the entity needs @Aggregation.default annotations, which defines which aggregation methods are supported. This can only be done on views that are not transactional.
Note
Source: CDS View /DMO/FSA_I_Chart
define view entity /DMO/FSA_I_Chart
as select from zfsa_chart_a
...
{
key id as ID,
...
@EndUserText.label : 'Minimal Net Amount'
@Aggregation.default: #MIN
integer_value as MinAmount,
@EndUserText.label : 'Maximal Net Amount'
@Aggregation.default: #MAX
integer_value as MaxAmount,
@EndUserText.label : 'Average Net Amount'
@Aggregation.default: #AVG
integer_value as AvgAmount,
...
}
After that the @UI.chart can be defined. Please note, that the attribute measures contains the properties of the aggregation methods. If it is just a property of the entity, like "integerValue", the chart won't be displayed. The first property in the attribute dimensions has the default dimension. The second property is the category into which a drill down is possible.
The added actions to the attribute actions are shown in the chart toolbar.
Note
Source: CDS View /DMO/FSA_C_ChartTP
// Search Term #ChartSection
@UI.chart: [
{
qualifier: 'Test',
title: 'Chart (#ChartSection)',
chartType: #COLUMN,
dimensions: ['Dimensions', 'CriticalityCode'],
measures: ['MaxAmount'],
dimensionAttributes: [
{

measureAttributes: [
{
measure: 'MaxAmount',
role: #AXIS_1
}
],
actions: [{ type: #FOR_ACTION, dataAction: 'updateChart', label: 'Action at Chart' }]
}
]
Lastly the chart needs to be added to the @UI.facet annotation.
