• What is the cause and solution for SAP error message SDDL_PARSER_MSG303 - Literals not allowed in ON condition of a to-parent association ?

  The SAP error message SDDL_PARSER_MSG303 indicates that there is an issue with the use of literals in the ON condition of a to-parent association in your data model. This typically occurs in the context of SAP HANA or when working with the SAP Data Warehouse or similar environments where you define associations between entities.
  Cause:
  The error arises when you attempt to use a literal value (like a string or number) directly in the ON condition of a to-parent association. In SAP's data modeling, associations are meant to define relationships between entities, and the ON condition should reference fields or attributes rather than hard-coded values.
  Solution:
  To resolve this error, you need to modify the ON condition of your to-parent association to ensure that it references the appropriate fields instead of using literals. Here’s how you can do that:
  
  
  Identify the Association: Locate the to-parent association in your data model that is causing the error.
  
  
  Modify the ON Condition: Change the ON condition to use fields from the entities involved in the association. For example, instead of writing something like:
  ON childEntity.field = 'literalValue'
  You should write:
  ON childEntity.field = parentEntity.field
  
  
  Validate the Model: After making the changes, validate your data model to ensure that there are no further errors.
  
  
  Test the Association: Run a test query or report that utilizes the association to confirm that it works as expected.
  
  
  Related Information:
  
  Documentation: Refer to the SAP documentation for data modeling and associations to understand the correct syntax and usage of associations.
  SAP Community: Engage with the SAP Community forums for additional insights and examples from other users who may have encountered similar issues.
  Best Practices: Familiarize yourself with best practices for defining associations in SAP models to avoid similar errors in the future.
  
  By following these steps, you should be able to resolve the SDDL_PARSER_MSG303 error and successfully define your associations without using literals in the ON condition.
