• What is the cause and solution for SAP error message DMEE381 - Error in node &1: trailer only possible with level 1 ?

  The SAP error message DMEE381 indicates that there is an issue with the configuration of the Data Medium Exchange Engine (DMEE) in your SAP system, specifically related to the structure of the DMEE tree. This error occurs when a trailer node is defined at a level other than level 1 in the DMEE tree structure.
  Cause:
  The error arises when:
  
  A trailer node is incorrectly placed in the DMEE tree structure. In DMEE, a trailer node is expected to be at level 1, which means it should be a direct child of the root node.
  The configuration of the DMEE tree does not adhere to the expected hierarchy, leading to the system not being able to process the trailer node correctly.
  
  Solution:
  To resolve the DMEE381 error, you can follow these steps:
  
  
  Check the DMEE Tree Structure:
  
  Go to the DMEE transaction (transaction code: DMEE).
  Open the relevant DMEE tree that is causing the error.
  Verify the placement of the trailer node. Ensure that it is positioned at level 1 (directly under the root node).
  
  
  
  Adjust the Node Levels:
  
  If the trailer node is not at level 1, you will need to move it to the correct position.
  You can do this by dragging the node to the appropriate level or by editing the properties of the node to change its hierarchy.
  
  
  
  Validate the Configuration:
  
  After making changes, validate the DMEE tree to ensure that there are no other structural issues.
  Use the "Check" function in the DMEE transaction to identify any additional errors.
  
  
  
  Test the Configuration:
  
  Once the adjustments are made, perform a test run of the DMEE process to ensure that the error is resolved and that the output is generated correctly.
