• What is the cause and solution for SAP error message DMEE_ABA351 - List of levels contains gaps or is not in ascending order ?

  The SAP error message DMEE_ABA351 indicates that there is an issue with the configuration of the Data Medium Exchange Engine (DMEE) in SAP, specifically related to the structure of the levels defined in the DMEE tree. This error typically arises when the levels in the DMEE tree are not properly defined, either because they contain gaps or are not in ascending order.
  Cause:
  
  Gaps in Levels: The levels defined in the DMEE tree must be continuous. If there are any missing levels (e.g., if you have levels 1, 2, and 4, but no level 3), this will trigger the error.
  Non-ascending Order: The levels must be defined in ascending order. If they are defined in a random order (e.g., level 3 followed by level 1), this will also cause the error.
  
  Solution:
  To resolve the DMEE_ABA351 error, follow these steps:
  
  
  Access the DMEE Configuration:
  
  Go to transaction code DMEE in SAP.
  
  
  
  Check the DMEE Tree:
  
  Open the relevant DMEE tree that is causing the error.
  Review the levels defined in the tree structure.
  
  
  
  Identify Gaps or Order Issues:
  
  Ensure that all levels are present without any gaps. For example, if you have levels 1, 2, 3, and 4, make sure none are missing.
  Check that the levels are in ascending order. They should be numbered sequentially (1, 2, 3, etc.).
  
  
  
  Correct the Levels:
  
  If you find any gaps, add the missing levels.
  If the levels are not in ascending order, rearrange them to ensure they follow the correct sequence.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save the DMEE tree configuration.
  
  
  
  Test the Configuration:
  
  Run the DMEE process again to ensure that the error has been resolved.

  Documentation: Refer to SAP Help documentation for more detailed information on configuring DMEE trees and understanding the structure of levels.
  
  By following these steps, you should be able to resolve the DMEE_ABA351 error and ensure that your DMEE configuration is correct.
