  The SAP error message /EACC/DMB002 DataSource &1 already created with InfoSource &2 typically occurs in the context of SAP Data Warehousing or SAP BW (Business Warehouse) when you are trying to create a DataSource that has already been defined for a specific InfoSource. This can happen during the process of data modeling or when setting up data extraction from a source system.
  Cause:
  
  Duplicate DataSource: The DataSource you are trying to create already exists in the system for the specified InfoSource. This can happen if the DataSource was previously created and not deleted or if there was an attempt to create it again without checking for existing definitions.
  Incorrect Configuration: There may be a misconfiguration in the DataSource or InfoSource settings that leads to this error.
  Transport Issues: If you are transporting objects between systems (e.g., from development to production), there may be conflicts with existing objects.

  Use a Different Name: If you need to create a new DataSource, consider using a different name or identifier that does not conflict with existing DataSources.
  
  
  Check Transport Requests: If this issue arises after a transport, ensure that the transport did not overwrite or conflict with existing objects. You may need to adjust the transport request or resolve conflicts manually.
