  The SAP error message ESH_HANA_ADMIN050 indicates that there is an issue with attempting to modify a TREX index via the HANA Database (HDB) Proxy API. This error typically arises in the context of SAP's Enterprise Search (ESH) or when working with the HANA database and its integration with TREX (Text Retrieval and Extraction).
  Cause:
  The error can occur due to several reasons:
  
  Incorrect API Usage: The HDB Proxy API is not intended for direct modifications of TREX indexes. This error suggests that there is an attempt to perform an operation that is not supported by the API.

  Solution:
  To resolve the error, consider the following steps:
  
  
  Review API Documentation: Ensure that you are using the correct API for the intended operation. The HDB Proxy API should not be used for modifying TREX indexes directly.

  Use Correct Tools: If you need to modify TREX indexes, use the appropriate tools or APIs designed for that purpose, such as the TREX administration tools.
  
  
  Permissions Check: Ensure that the user or service account has the necessary permissions to perform the operation. You may need to consult with your system administrator to verify and adjust permissions.
