• What is the cause and solution for SAP error message /EACC/DMB003 - InfoSource &2 already created with DataSource &3 ?

  The SAP error message /EACC/DMB003 InfoSource &2 already created with DataSource &3 typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when you are trying to create or activate an InfoSource that has already been defined in the system with the same DataSource.
  Cause:
  
  Duplicate InfoSource: The error indicates that an InfoSource with the same name (represented by &2) already exists in the system and is associated with the specified DataSource (represented by &3).
  DataSource Already Linked: The DataSource you are trying to use is already linked to an existing InfoSource, which prevents the creation of a new one with the same identifiers.
  
  Solution:
  
  
  Check Existing InfoSources: 
  
  Go to the InfoSource maintenance transaction (e.g., RSA1) and check if the InfoSource with the name &2 already exists.
  If it does, you can either use the existing InfoSource or modify it as needed.
  
  
  
  Use a Different Name: 
  
  If you need to create a new InfoSource, consider using a different name that does not conflict with existing InfoSources.
  
  
  
  Delete or Modify Existing InfoSource: 
  
  If the existing InfoSource is no longer needed, you can delete it. However, be cautious as this may affect any existing data flows or reports that rely on it.
  Alternatively, you can modify the existing InfoSource to accommodate your requirements.
  
  
  
  Check DataSource Configuration: 
  
  Ensure that the DataSource &3 is correctly configured and linked to the appropriate InfoSource. If necessary, reassign it to the correct InfoSource.
