  The SAP error message RSD_TREX148 typically relates to issues encountered during the optimization of a query in the SAP BW (Business Warehouse) environment, particularly when using the TREX (Text Retrieval and Extraction) engine. This error can occur during the execution of a query that involves optimization steps, which are intended to improve performance.
  Cause:
  
  Data Volume: The query may be processing a large volume of data, leading to timeouts or resource constraints.
  System Resources: Insufficient memory or CPU resources on the server can cause optimization processes to fail.
