• What is the cause and solution for SAP error message RSRTS_CDS202 - Field &1 will be ignored in BW query. Data contained in field &2. ?

  The SAP error message RSRTS_CDS202 typically occurs in the context of SAP BW (Business Warehouse) queries when there is a mismatch or issue with the fields being used in a query that is based on a Core Data Services (CDS) view. The message indicates that a specific field (denoted as &1) will be ignored in the query because the data contained in that field (denoted as &2) is not compatible or cannot be processed as expected.
  Cause:
  
  
  Field Compatibility: The field specified as &1 may not be compatible with the data type or structure expected in the BW query. This can happen if the field is not properly defined in the underlying CDS view or if it has been changed after the query was created.
  
  
  Aggregation Issues: If the field is being used in an aggregation context but does not support aggregation, it may be ignored.
  
  
  Data Source Changes: Changes in the underlying data source (like the CDS view) after the query has been created can lead to this error. For example, if a field was removed or its data type was changed.
  
  
  Field Selection: The field may not be selected correctly in the query definition, or it may not be available in the context of the query.
  
  
  Solution:
  
  
  Check Field Definitions: Review the definitions of the fields in the CDS view to ensure that they are correctly defined and compatible with the BW query.
  
  
  Update Query: If the underlying CDS view has changed, you may need to update the BW query to reflect these changes. This can involve re-selecting fields or adjusting the query structure.
  
  
  Aggregation Settings: If the field is being used in an aggregation context, ensure that it is set up correctly to support aggregation.
  
  
  Rebuild the Query: In some cases, it may be necessary to rebuild the query from scratch to ensure that all fields are correctly aligned with the underlying data model.
