This typically occurs in the context of SAP BW (Business Warehouse) when there are inconsistencies between the data model and the underlying index in the TREX (Text Retrieval and Extraction) engine.
  Cause:
  
  Data Model Changes: The attribute may have been removed or modified in the data model (e.g., InfoObject or InfoProvider) but the corresponding index in TREX has not been updated.
  Index Corruption: There may be corruption or inconsistencies in the TREX index that lead to the attribute being reported as deleted.
  Transport Issues: If changes were transported from one system to another, the transport might not have included all necessary objects or the transport might have failed.

  Transport Check: If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included and that there were no errors during the transport process.
