• What is the cause and solution for SAP error message SADL_EXPOSURE078 - Field prefix for assoc. '&1' with reverse assoc. of '&2' is not allowed ?

  The SAP error message SADL_EXPOSURE078 indicates that there is an issue with the field prefix for an association in the context of the SAP ABAP programming model, particularly when using the SAP Data Access Layer (SADL). This error typically arises when there is an attempt to use a field prefix that is not allowed for a reverse association.
  Cause:
  The error occurs due to the following reasons:
  
  Invalid Field Prefix: The field prefix specified for the association is not valid for the reverse association. This can happen if the field prefix is not defined correctly in the data model or if it does not match the expected naming conventions.
  Association Configuration: The associations between entities may not be configured correctly in the underlying data model, leading to conflicts when trying to access or manipulate data.
  Modeling Errors: There may be errors in the way the data model is defined, such as incorrect relationships or missing associations.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check the Data Model:

  Verify that the reverse associations are properly configured and that they match the expected structure.
  
  
  
  Adjust Field Prefixes:
  
  If you are using a specific field prefix in your query or data access logic, ensure that it is appropriate for the association you are working with. You may need to remove or change the prefix to align with the expected configuration.
  
  
  
  Review Association Definitions:
  
  Check the definitions of the associations in the CDS (Core Data Services) views or the underlying database tables. Ensure that the associations are correctly defined and that there are no discrepancies.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for SADL and the specific data model you are working with. This can provide insights into the correct usage of field prefixes and associations.
