• What is the cause and solution for SAP error message DMEE352 - First tree node (&1) has nodes on the same level ?

  The SAP error message DMEE352 indicates that there is an issue with the structure of the DMEE (Data Medium Exchange Engine) tree configuration. Specifically, it means that the first tree node has multiple child nodes at the same level, which is not allowed in the DMEE tree structure.
  Cause:
  The error occurs when:
  
  You have defined multiple nodes at the same hierarchical level under a single parent node in the DMEE tree.
  The DMEE tree structure is not properly configured, leading to ambiguity in how the data should be processed.
  
  Solution:
  To resolve the DMEE352 error, you can follow these steps:
  
  
  Check the DMEE Tree Structure:
  
  Open the DMEE tree in the SAP system.
  Navigate to the first tree node mentioned in the error message (indicated by &1).
  Review the child nodes under this parent node.
  
  
  
  Adjust the Hierarchy:
  
  Ensure that each child node under the parent node is uniquely defined and does not have siblings at the same level that could cause confusion.
  If you have multiple nodes that need to be at the same level, consider restructuring the tree to create a new parent node for these nodes.
  
  
  
  Validate the Tree:
  
  After making changes, validate the DMEE tree to ensure that there are no further structural issues.
  Use the "Check" function in the DMEE transaction to identify any remaining errors.
  
  
  
  Test the Configuration:
  
  Once the tree structure is corrected, test the DMEE configuration to ensure that it processes data correctly without generating errors.
  
  
  
  Related Information:
  
  Transaction Codes: You can access the DMEE configuration using transaction code DMEE.
  Documentation: Refer to SAP documentation or help files for detailed guidance on configuring DMEE trees and understanding the hierarchy rules.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates related to DMEE errors.
  
  By following these steps, you should be able to resolve the DMEE352 error and ensure that your DMEE tree is correctly structured for data processing.
