• What is the cause and solution for SAP error message SDDL_PARSER_MSG186 - Parameters must not be used in the associations ON condition. ?

  The SAP error message SDDL_PARSER_MSG186 indicates that there is an issue with the use of parameters in the ON condition of an association in your SAP system. This typically occurs in the context of SAP HANA or when working with Core Data Services (CDS) views, where associations are defined.
  Cause:
  The error arises when you attempt to use parameters in the ON condition of an association. In SAP CDS views, the ON condition is meant to define how two entities are related, and it does not support the use of parameters. Parameters are typically used in the WHERE clause or in the selection criteria, but not in the association definition.
  Solution:
  To resolve this error, you should:
  
  
  Review the Association Definition: Check the association in your CDS view and ensure that you are not using any parameters in the ON condition. The ON condition should only reference fields from the entities being associated.
  
  
  Refactor the Logic: If you need to filter or modify the association based on parameters, consider moving that logic to the WHERE clause of your query instead of the ON condition.
  
  
  Example Correction:
  
  Incorrect:
  define association to AnotherEntity as _AnotherEntity
  on AnotherEntity.field = :parameter
  
  Correct:
  define association to AnotherEntity as _AnotherEntity
  on AnotherEntity.field = this.field
  
  
  
  
  Use Parameters in the Query: If you need to filter results based on parameters, you can do so in the main query that consumes the CDS view, rather than in the association itself.
  
  
  Related Information:
  
  Documentation: Refer to the official SAP documentation on Core Data Services (CDS) for more details on how to properly define associations and use parameters.
  SAP Community: You can also check the SAP Community forums for discussions related to this error, as other users may have encountered similar issues and shared their solutions.
  Debugging: If you continue to face issues, consider using the SAP ABAP debugger or transaction codes like SE11 or SE80 to analyze the data model and associations in detail.
  
  By following these steps, you should be able to resolve the SDDL_PARSER_MSG186 error and correctly define your associations in SAP.
