• What is the cause and solution for SAP error message SADL_GEN_DRFT_MSG107 - Join between active CDS view &1 and draft view &2 not generated (Union) ?

  The SAP error message SADL_GEN_DRFT_MSG107 indicates that there is an issue with generating a join between an active Core Data Services (CDS) view and a draft view. This error typically arises in the context of using the SAP Draft Framework, which is used for managing draft data in applications.
  Cause:
  The error message suggests that the system is unable to generate a join between the specified active CDS view (&1) and the draft view (&2). This can occur due to several reasons:
  
  Incompatible Structures: The active CDS view and the draft view may have incompatible structures or fields that prevent a successful join.
  Union Restrictions: The error specifically mentions "Union," which implies that there may be restrictions on how the two views can be combined. For example, the fields in both views must match in terms of data types and cardinality.
  Missing Annotations: The necessary annotations for draft handling may be missing in either the active or draft CDS view.
  Incorrect Join Conditions: The join conditions defined in the CDS views may not be valid or may not align properly with the draft view.
  Technical Issues: There could be underlying technical issues or bugs in the system that are causing the join generation to fail.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check View Definitions: Review the definitions of both the active CDS view and the draft view. Ensure that they have compatible structures and that the fields you intend to join on are correctly defined.
  
  
  Verify Annotations: Ensure that both views have the necessary annotations for draft handling. For example, check for annotations like @ObjectModel.draftEnabled: true in the draft view.
  
  
  Review Join Conditions: Examine the join conditions in the CDS views. Make sure that the fields used for joining are correctly specified and that they match in terms of data types.
  
  
  Test with Simplified Views: If possible, create simplified versions of the active and draft views to isolate the issue. This can help identify whether the problem lies in the complexity of the views or in specific fields.
  
  
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as there may be bug fixes related to this issue.
  
  
  Consult Documentation: Refer to the SAP documentation for the Draft Framework and CDS views to ensure that you are following best practices.
