• What is the cause and solution for SAP error message SADL_EXPOSURE074 - Key mapping of association '&1' of entity '&2' is not complete ?

  The SAP error message SADL_EXPOSURE074 indicates that there is an issue with the key mapping of an association in a data model, specifically in the context of the SAP ABAP programming environment and the SAP Data Access Layer (SADL). This error typically arises when the key mapping for an association between entities is incomplete or not properly defined.
  Cause:
  The error can occur due to several reasons:
  
  Incomplete Key Mapping: The association defined in the data model does not have a complete set of keys mapped. This means that not all required fields for the association are specified.
  Incorrect Configuration: There may be a misconfiguration in the data model or the underlying database tables that leads to the association not being properly recognized.
  Changes in Data Model: If there have been recent changes to the data model, such as adding or removing fields, the key mapping may not have been updated accordingly.
  Missing Annotations: The necessary annotations that define the key mapping may be missing in the metadata.
  
  Solution:
  To resolve the SADL_EXPOSURE074 error, you can follow these steps:
  
  
  Check Key Mapping:
  
  Review the association definition in your data model. Ensure that all required keys are correctly mapped.
  Verify that the keys in the source entity match the keys in the target entity of the association.
  
  
  
  Update Data Model:
  
  If there have been changes to the data model, ensure that all associations are updated to reflect these changes.
  Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to check and modify the data model.
  
  
  
  Review Annotations:
  
  Check the annotations in your CDS (Core Data Services) views or other relevant metadata. Ensure that the key mapping annotations are correctly defined.
  
  
  
  Test the Association:
  
  After making changes, test the association to ensure that it works as expected. You can do this by executing the relevant queries or transactions that utilize the association.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or community forums for additional guidance on key mapping and associations in SADL.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the application to trace where the key mapping is failing. This may involve checking the runtime behavior of the data access layer.
