  The SAP error message "SADL_GW_DT_SB_UI201 Multiple Roots found" typically occurs in the context of the SAP Gateway and the SAP Data Access Layer (SADL). This error indicates that the system has encountered multiple root entities when trying to resolve a data model, which can lead to ambiguity in the data retrieval process.
  Cause:
  
  Multiple Root Entities: The error arises when the data model defined in the SADL configuration has more than one root entity. This can happen if the data model is not properly defined or if there are multiple entities that can serve as the starting point for the data retrieval.

  Adjust Query Logic: If you are using a custom query, review the logic to ensure that it is correctly targeting a single root entity. You may need to adjust the query to specify which entity should be the root.
  Debugging: Use debugging tools to trace the execution of the query and identify where the multiple roots are being introduced. This can help pinpoint the exact issue in the model or query.
  Consult Documentation: Refer to SAP documentation for SADL and the specific data model you are working with. There may be guidelines or best practices that can help resolve the issue.
