Smart SAP Assistant

• What is the cause and solution for SAP error message SADL_EXPOSURE057 - Entity &2 cannot not be draft enabled because its base view &1 is not ?

  The SAP error message SADL_EXPOSURE057 indicates that you are trying to enable a specific entity for draft handling, but the base view associated with that entity is not configured to support draft functionality. This is a common issue when working with the SAP ABAP programming model for Fiori applications, particularly when using the SAP Data Layer (SADL).
  Cause:
  The error occurs due to the following reasons:
  
  Base View Not Draft Enabled: The base view (the underlying data model) of the entity you are trying to draft enable does not have draft capabilities. In SAP, for an entity to support draft operations, its base view must also be configured to support drafts.
  Configuration Issues: There may be a misconfiguration in the definition of the base view or the entity itself.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Base View Configuration:
  
  Open the base view (the one referenced in the error message) in the ABAP Development Tools (ADT) or the relevant transaction.
  Ensure that the base view is configured to support draft handling. This typically involves setting the appropriate properties in the view definition.
  
  
  
  Enable Draft Handling:
  
  If the base view is not draft-enabled, you will need to enable draft handling. This can usually be done by:
  
  Modifying the base view to include draft support.
  Ensuring that the necessary annotations for draft handling are present in the view definition (e.g., @ObjectModel.draftEnabled: true).
  
  
  
  
  
  Check Annotations:
  
  Verify that the annotations for both the base view and the entity are correctly defined. Look for annotations related to draft handling and ensure they are consistent.
  
  
  
  Rebuild and Activate:
  
  After making the necessary changes, rebuild and activate the base view and the entity to ensure that the changes take effect.
  
  
  
  Test the Changes:
  
  After enabling draft handling, test the entity to confirm that it can now be draft-enabled without triggering the error.
  
  
  
  Related Information:
  
  Draft Handling in SAP: Draft handling is a feature in SAP that allows users to create and edit data in a temporary state before saving it permanently. This is particularly useful in Fiori applications where users may want to make multiple changes before committing them.
  SAP Fiori Elements: If you are using Fiori Elements, ensure that your annotations are correctly set up to leverage draft capabilities.
  SAP Documentation: Refer to the official SAP documentation for detailed guidelines on enabling draft handling in your specific version of SAP.
  
  By following these steps, you should be able to resolve the SADL_EXPOSURE057 error and successfully enable draft handling for your entity.
