Here's a structured blog post that outlines the steps for creating F4 help using domain values in RAP.
Creating F4 Help Using Domain Values in RAP
In SAP RAP (Restful Application Programming), F4 help allows users to select predefined values efficiently. This blog post guides you through the process of integrating F4 help using domain values.
Step 1: Establish a Domain Element
Start by defining a domain element with the required value range. This ensures that the F4 help dropdown is populated with relevant selections.
Step 2: Create an Interface View
Utilize the domain element alongside DDCDS_CUSTOMER_DOMAIN_VALUE_T to retrieve the corresponding fields.
Step 3: Associate the Domain Interface View
Once the domain interface view is created, establish its association with the root interface view to make it accessible within the RAP model.
Step 4: Use Fields in the Projection
Now that the association is established, integrate the fields from the domain interface view within the projection to display the respective options in UI elements.
Step 5: Update Metadata
Ensure that the domain interface view is incorporated in the metadata file using the appropriate annotations, enabling proper functionality within the RAP framework.
Step 6: Validate F4 Help Implementation
After completing the above steps, the F4 help functionality should be fully operational, displaying the relevant predefined values for user selection.
