AFWCH_FL044 - Details

• The SAP error message AFWCH_FL044, which states "A single filter already exists for this characteristic," typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are trying to apply a filter to a characteristic in a query or report, but a filter for that characteristic has already been defined.
  
  Cause:
  
  Existing Filter: The primary cause of this error is that a filter for the specified characteristic has already been applied in the query or report. SAP does not allow multiple filters for the same characteristic to avoid ambiguity in data retrieval.
  Query Design: This can happen during the design of a query in the BEx Query Designer or when using a report that is based on a query that already has a filter set for that characteristic.
  
  
  Solution:
  
  Check Existing Filters: Review the filters that are currently applied to the query. You can do this in the BEx Query Designer
