• What is the cause and solution for SAP error message RSRTS_CDS021 - Filters on texts/attributes will act on corresponding key field (at &1) ?

  The SAP error message RSRTS_CDS021 typically occurs in the context of using SAP BW (Business Warehouse) or SAP HANA when working with Composite Data Sources (CDS) views or queries. This message indicates that filters applied to text fields or attributes in a query will be applied to the corresponding key fields instead. This can lead to unexpected results if the user is not aware of this behavior.
  Cause:
  The error arises because the query is trying to filter on a text or attribute field, but the underlying data model is designed to filter based on the key field associated with that text or attribute. In SAP BW and HANA, text fields are often linked to key fields, and filtering on a text field will not work as expected unless the key field is also included in the query.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check Query Design: Review the query design in the Query Designer. Ensure that you are using the correct key fields in conjunction with the text fields. If you want to filter based on a text field, make sure the corresponding key field is also included in the query.
  
  
  Modify Filters: If you are applying filters on text fields, consider modifying your filters to use the key fields instead. This will ensure that the filtering works as intended.
  
  
  Use Key Fields in Selection: When creating or modifying your query, include the key fields that correspond to the text fields you are filtering on. This will allow the filters to work correctly.
  
  
  Documentation and Help: Refer to SAP documentation or help resources for more information on how to work with CDS views and queries. Understanding the relationships between key fields and text fields can help prevent this issue in the future.
  
  
  Testing: After making changes, test the query to ensure that it returns the expected results. Adjust filters as necessary based on the output.
