This error indicates that the on-condition specified for an association is not valid or is inconsistent with the underlying data model.
  Causes:
  
  Incorrect Association Definition: The on-condition for the association may reference fields that do not exist or are not compatible in the associated entities.
  Data Type Mismatch: The fields used in the on-condition may have different data types, leading to inconsistency.

  Logical Errors: There may be logical errors in the way the association is defined, such as circular references or incorrect join conditions.
  
  Solutions:
  
  
  Review the Association Definition: Check the association definition in the CDS view for any typos or incorrect field references. Ensure that the fields used in the on-condition are correctly spelled and exist in the associated entities.
  
  
  Check Data Types: Ensure that the data types of the fields used in the on-condition match. If there is a mismatch, you may need to cast the fields to the appropriate type.
  
  
  Validate the CDS View: Use the ABAP Development Tools (ADT) in Eclipse or the transaction code SE11 to validate the CDS view. This can help identify any inconsistencies or errors in the definition.
  
  
  Test the Association: If possible, create a simple test case to isolate the issue. This can help determine if the problem lies with the specific association or if it is a broader issue with the CDS view.
