You can use OData If expressions for specific annotations in SAP Fiori elements for OData V4.

The following annotations are supported:

  • FieldControl

  • UI.Hidden

  • Core.OperationAvailable

  • SAP__capabilities.UpdateRestrictions

  • SAP__capabilities.InsertRestriction

  • SAP__capabilities.DeleteRestriction

Sample Code:

Example on FieldControl

<Annotations Target="sap.fe.core.FieldEdit.RootEntity/FieldControlDynamicIf"> 
    <Annotation Term="com.sap.vocabularies.Common.v1.FieldControl"> 
        <If> 
            <Eq> 
                <Path>FieldControlDynamicIfValue</Path> 
                <Int>5</Int> 
            </Eq> 
            <EnumMember>Common.FieldControlType/ReadOnly</EnumMember> 
            <EnumMember>Common.FieldControlType/Optional</EnumMember> 
        </If> 
    </Annotation> 
</Annotations>

Sample Code:

<Annotation Term="Capabilities.NavigationRestrictions"> 
    <Record Type="Capabilities.NavigationRestrictionsType"> 
        <PropertyValue Property="RestrictedProperties"> 
            <Collection> 
                <Record Type="Capabilities.NavigationPropertyRestriction"> 
                    <PropertyValue Property="NavigationProperty" NavigationPropertyPath="_Item" /> 
                    <PropertyValue Property="InsertRestrictions">

                        </Record> 
                    </PropertyValue> 
                    <PropertyValue Property="UpdateRestrictions">

Support of odata.concat function

The odata.concat function is supported on the title of the object page header. You can use it to set the title as a concatenation of a text and value from the database.

Sample Code:

<Annotations Target="SAP__self.BusinessPartner"> 
    <Annotation Term="com.sap.vocabularies.UI.v1.HeaderInfo"> 
        <Record Type="com.sap.vocabularies.UI.v1.HeaderInfoType"> 
            <PropertyValue Property="TypeName" String="Business Partner" /> 
            <PropertyValue Property="TypeNamePlural" String="Business Partners" /> 
            <PropertyValue Property="Title"> 
                <Record Type="com.sap.vocabularies.UI.v1.DataField"> 
                    <PropertyValue Property="Label" String="Name" /> 
                    <PropertyValue Property="Value"> 
                        <Apply Function="odata.concat"> 
                            <Path>CompanyName</Path> 
                            <String /> 
                            <Path>LegalForm</Path> 
                        </Apply> 
                    </PropertyValue> 
                </Record>
