• What is the cause and solution for SAP error message RS_B4HANA_RC091 - LeftOuter: Add Filter Value to On-Condition setting not supported. ?

  The SAP error message RS_B4HANA_RC091 with the description "LeftOuter: Add Filter Value to On-Condition setting 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 generally arises when you attempt to add a filter value to an "ON" condition in a left outer join. In SAP BW/4HANA, certain operations and configurations are restricted, and adding filter values directly to the "ON" condition of a left outer join is not supported. This is because left outer joins are designed to include all records from the left table regardless of whether there is a match in the right table, and adding filters can contradict this behavior.
  Solution:
  To resolve this error, consider the following approaches:
  
  
  Review Join Conditions: Check the join conditions in your CompositeProvider or data model. Ensure that you are not trying to apply filters directly in the "ON" clause of a left outer join.
  
  
  Use WHERE Clause: Instead of applying filters in the "ON" condition, you can apply them in the "WHERE" clause of your query or in the data model itself. This way, you can still filter the results after the join has been performed.
  
  
  Change Join Type: If the logic of your data model allows, consider changing the join type from left outer to inner join or another type that fits your requirements without needing to filter in the "ON" condition.
  
  
  Data Model Redesign: If the above solutions do not work, you may need to redesign your data model to accommodate the requirements without violating the constraints of the left outer join.
  
  
  Consult Documentation: Refer to the official SAP documentation for BW/4HANA or the specific version you are using. There may be additional guidelines or best practices for handling joins and conditions.
  
  
  Related Information:

  By following these steps, you should be able to resolve the error and successfully configure your data model.
