• What is the cause and solution for SAP error message RS_B4HANA_RC090 - LeftOuter: Add Filter Value to On-Condition setting is not supported. ?

  The SAP error message RS_B4HANA_RC090 with the description "LeftOuter: Add Filter Value to On-Condition setting is not supported" typically occurs in the context of SAP BW/4HANA or SAP BW on HANA when working with data models, particularly when defining joins or conditions in CompositeProviders or other data modeling scenarios.
  Cause:
  This error arises when you attempt to use a filter condition in a Left Outer Join that is not supported. In SAP BW/4HANA, certain types of joins (like Left Outer Joins) have restrictions on how conditions can be applied. Specifically, adding filter values to the "On-Condition" of a Left Outer Join is not allowed because it can lead to ambiguous results or conflicts in the data retrieval process.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Review Join Conditions: Check the join conditions in your CompositeProvider or InfoProvider. Ensure that you are not trying to apply filter values directly in the "On-Condition" of a Left Outer Join.
  
  
  Use Inner Joins: If possible, consider using an Inner Join instead of a Left Outer Join if the business logic allows it. Inner Joins do not have the same restrictions regarding filter conditions.
  
  
  Move Filters to Where Clause: If you need to filter data, consider moving the filter conditions to the "Where" clause of the query or to the selection criteria of the data model instead of applying them in the join condition.
  
  
  Check Documentation: Refer to the SAP documentation for BW/4HANA or the specific version you are using to understand the limitations and best practices for defining joins and conditions.
  
  
  Consult SAP Notes: Check for any relevant SAP Notes or updates that might address this issue or provide additional guidance.
  
  
  Testing: After making changes, test the data model to ensure that it behaves as expected and that the error no longer occurs.
  
  
  Related Information:
  
  SAP BW/4HANA Documentation: Review the official SAP documentation for BW/4HANA, which provides guidelines on data modeling, joins, and conditions.
  SAP Community: Engage with the SAP Community forums where other users may have encountered similar issues and can provide insights or solutions.
  SAP Support: If the issue persists, consider reaching out to SAP Support for assistance, especially if you suspect it may be a bug or require deeper technical investigation.
  
  By following these steps, you should be able to resolve the RS_B4HANA_RC090 error and successfully configure your data model.
