• What is the cause and solution for SAP error message /EACC/DMB021 - DataSource &1 has not yet been created ?

  The SAP error message /EACC/DMB021 DataSource &1 has not yet been created typically occurs in the context of SAP Data Warehousing or SAP BW (Business Warehouse) when a DataSource that is being referenced does not exist in the system. This can happen for various reasons, such as incorrect configuration, missing DataSource creation, or issues during the data extraction process.
  Cause:
  
  DataSource Not Created: The most common cause is that the DataSource specified (indicated by &1 in the error message) has not been created in the SAP system.
  Incorrect Configuration: There may be a misconfiguration in the settings or parameters related to the DataSource.
  Transport Issues: If the DataSource was supposed to be transported from another system (like Development to Production), it may not have been transported correctly.
  Authorization Issues: The user may not have the necessary authorizations to access the DataSource, leading to the perception that it does not exist.
  
  Solution:
  
  
  Create the DataSource: 
  
  Go to the SAP BW system and create the DataSource using transaction code RSA1 (Data Warehousing Workbench).
  Navigate to the appropriate area (e.g., InfoSource, DataSource) and create the DataSource if it does not exist.
  
  
  
  Check Configuration:
  
  Verify the configuration settings for the DataSource. Ensure that all necessary parameters are correctly set.
  Check if the DataSource is active and properly configured for data extraction.
  
  
  
  Transport Check:
  
  If the DataSource was supposed to be transported, check the transport logs to ensure that it was successfully transported.
  If it was not transported, you may need to create it manually in the target system or re-transport it.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to access the DataSource. Check the roles and authorizations assigned to the user.
  
  
  
  Check for Naming Issues:
  
  Ensure that there are no typographical errors in the DataSource name being referenced. Sometimes, the error can be due to a simple naming mismatch.
