• What is the cause and solution for SAP error message DBMAN120 - TREX index as a value restriction only possible if accessing BWA/SAP HANA ?

  The SAP error message DBMAN120 indicates that there is an issue related to the TREX (Text Retrieval and Extraction) index, specifically that a value restriction is only possible when accessing BWA (Business Warehouse Accelerator) or SAP HANA. This error typically arises in scenarios where you are trying to perform a query or operation that involves value restrictions on a TREX index, but the underlying database does not support this feature.
  Cause:

  Use BWA or SAP HANA: If possible, switch to using BWA or SAP HANA as your database. These databases are designed to work seamlessly with TREX and support value restrictions.
  Modify the Query: Review and modify the query to avoid using value restrictions that are not supported by the current database. This may involve changing how filters are applied or restructuring the query logic.
  Check Configuration: Ensure that the TREX and database configurations are correctly set up. This includes checking the connection settings and ensuring that the TREX server is properly integrated with the database.
