• What is the cause and solution for SAP error message RSRTS_CDS161 - Field &1: Filter will be ignored as characteristic &2 already filtered ?

  The SAP error message RSRTS_CDS161 indicates that there is a conflict in the filtering of characteristics in a query, specifically when using a Core Data Services (CDS) view in SAP BW or SAP HANA. The message states that a filter on a certain field (characteristic) is being ignored because that characteristic has already been filtered by another condition.
  Cause:
  This error typically occurs in the following scenarios:
  
  Redundant Filters: You have applied multiple filters on the same characteristic in your query. For example, if you filter on a characteristic like "Customer" in two different ways, the system will ignore the second filter since the first one has already defined the filtering criteria.
  Query Design: The query design may have overlapping filters that are not compatible with each other, leading to this message.
  Data Model Issues: There may be issues in the underlying data model or the way the CDS view is defined, causing conflicts in the filtering logic.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Filters: Check the filters applied to the query. Ensure that you are not applying multiple filters on the same characteristic. If you find redundant filters, remove or consolidate them.
  
  
  Modify Query Design: If you are using a query designer, review the query structure and ensure that each characteristic is only filtered once. You may need to adjust the logic of your query to avoid conflicts.
  
  
  Check CDS View: If you are using a CDS view, review the definition of the view to ensure that it does not have conflicting filters or logic that could lead to this error.
  
  
  Test Changes: After making adjustments, test the query again to see if the error persists. 
  
  
  Consult Documentation: If you are unsure about the filters or the query design, refer to SAP documentation or consult with a colleague who has experience with SAP BW or CDS views.
