• What is the cause and solution for SAP error message SADL_GEN_DRFT_MSG109 - CDS View &1 Annotation #TO_COMPOSITION_PARENT not found ?

  The SAP error message SADL_GEN_DRFT_MSG109 indicates that there is an issue with a Core Data Services (CDS) view where the annotation #TO_COMPOSITION_PARENT is not found. This error typically arises in the context of using the SAP ABAP programming model for Fiori applications, particularly when dealing with data modeling and annotations.
  Cause:
  The error is usually caused by one of the following reasons:
  
  
  Missing Annotation: The CDS view is expected to have a specific annotation (#TO_COMPOSITION_PARENT) that defines a relationship to a parent entity, but it is not defined in the view.
  
  
  Incorrect CDS View Definition: The CDS view may not be correctly defined to support the composition relationship, or the relationship may not be properly annotated.
  
  
  Versioning Issues: There may be versioning issues where the CDS view is not up to date with the latest changes or annotations.
  
  
  Transport Issues: If the CDS view was transported from one system to another, the necessary annotations may not have been included in the transport.
  
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the CDS View Definition:
  
  Open the CDS view in the ABAP Development Tools (ADT) or SE11 transaction.
  Ensure that the #TO_COMPOSITION_PARENT annotation is correctly defined in the CDS view. It should look something like this:
  @ObjectModel.compositionRoot: true
  @ObjectModel.toCompositionParent: [1] to_parent_entity
  define view your_cds_view as select from your_table
  ...
  
  
  
  
  Add the Missing Annotation:
  
  If the annotation is missing, add it to the CDS view definition. Make sure to define the relationship to the parent entity correctly.
  
  
  
  Activate the CDS View:
  
  After making changes, activate the CDS view to ensure that the changes take effect.
  
  
  
  Check for Dependencies:
  
  Ensure that any dependent views or entities are also correctly defined and activated.
  
  
  
  Transport Considerations:
  
  If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included in the transport.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for CDS views and annotations to ensure that you are using the correct syntax and semantics.
