  The SAP error message RSQBW409 indicates that there is an issue with the linking of objects in the SAP BW (Business Warehouse) environment. Specifically, it means that the objects you are trying to link (denoted as '&1' and '&2') are already linked to each other, which is causing a conflict.
  Cause:
  The error typically arises in scenarios where:
