  The SAP error message SRT_WSP728 indicates that there is a conflict with the Business Application ID (BAID) in the context of web service communication. Specifically, it means that the Business Application ID you are trying to use is already associated with another application in the specified system.

  Cause:
  
  Duplicate Registration: The same Business Application ID is being registered by multiple applications or services.
