• What is the cause and solution for SAP error message /EACC/DMB001 - DataSource &1 already created with InfoSource &3 ?

  The SAP error message /EACC/DMB001 DataSource &1 already created with InfoSource &3 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 error indicates that there is a conflict because the DataSource you are trying to create is already associated with the specified InfoSource.
  Cause:
  
  Duplicate DataSource: The DataSource you are attempting to create already exists in the system for the specified InfoSource.
  Incorrect Configuration: There may be a misconfiguration or misunderstanding regarding the DataSource and InfoSource relationship.
  Transport Issues: If you are transporting objects between systems, the DataSource might have been transported already, leading to this conflict.
  
  Solution:
  
  
  Check Existing DataSources: 
  
  Go to the DataSource maintenance transaction (e.g., RSA1 or RSO2) and check if the DataSource already exists for the specified InfoSource.
  If it exists, you may need to modify or use the existing DataSource instead of creating a new one.
  
  
  
  Delete or Rename: 
  
  If the existing DataSource is not needed, you can delete it (if permissible) or rename it to avoid the conflict.
  Ensure that you have the necessary authorizations to perform these actions.
  
  
  
  Use the Existing DataSource: 
  
  If the DataSource is valid and meets your requirements, consider using it instead of creating a new one.
  
  
  
  Check Transport Requests: 
  
  If this issue arises after a transport, verify the transport requests to ensure that the DataSource was not unintentionally included or modified.
