  The SAP error message RSRTS_CDS103 indicates that there is an issue with a restriction applied in a query, specifically that the restriction is not valid because it is not a characteristic key. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when working with Composite Data Sources (CDS) views or queries.
  Cause:
  
  Invalid Characteristic: The restriction applied in the query is referencing a field that is not a characteristic key. In SAP BW, characteristic keys are typically fields that can be used for filtering data in queries.
  Incorrect Query Design: The query may have been designed incorrectly, where a non-characteristic field is being used in a place where a characteristic is expected.

  Solution:
  
  
  Check the Query Design: Review the query design in the Query Designer. Ensure that all restrictions are applied to valid characteristic keys. You can do this by:
  
  Opening the query in the Query Designer.
  Checking the "Restrictions" section to ensure that only valid characteristic fields are being used.
  
  
  
  Modify the Restriction: If you find that a non-characteristic field is being used, either remove it or replace it with a valid characteristic key.
  
  
  Update the Data Model: If the underlying data model has changed, ensure that the query is updated to reflect these changes. This may involve:
  
  Refreshing the query.
  Rebuilding the query if necessary.
  
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on valid characteristic keys and how to structure queries correctly.
