  The SAP error message GQ058 indicates that a DataSource is already assigned to a specific table in the system, which can lead to conflicts or issues when trying to assign the same DataSource to another table. This error typically arises in the context of data extraction and loading processes, particularly when working with SAP BW (Business Warehouse) or SAP Data Services.

  Ensure that your data model is correctly set up and that there are no unnecessary duplications in DataSource assignments.
