• What is the cause and solution for SAP error message DMEE379 - Segment with reference ID &1 must have same level as segment &2 ?

  The SAP error message DMEE379 indicates that there is a structural issue in the Data Medium Exchange (DMEE) format configuration. Specifically, it means that a segment with a reference ID is not at the same hierarchical level as another segment, which is causing a validation error.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Hierarchical Structure Misalignment: The segments defined in the DMEE tree structure are not aligned correctly. Each segment must be at the same level in the hierarchy as its reference segment.
  Incorrect Configuration: The configuration of the DMEE tree may have been altered, leading to segments being placed incorrectly.
  Missing Parent Segment: A segment may be defined without a proper parent segment, which can lead to it being at a different level than expected.
  
  Solution:
  To resolve the DMEE379 error, follow these steps:
  
  
  Check the DMEE Tree Structure:
  
  Open the DMEE configuration in transaction code DMEE.
  Review the hierarchical structure of the segments. Ensure that the segments with reference IDs are correctly placed at the same level as their corresponding segments.
  
  
  
  Adjust Segment Levels:
  
  If you find that segments are incorrectly placed, adjust their levels by dragging them to the correct position in the hierarchy.
  Ensure that all segments that reference each other are at the same level.
  
  
  
  Validate Configuration:
  
  After making adjustments, validate the DMEE configuration to ensure there are no further errors.
  Use the "Check" function in the DMEE transaction to identify any remaining issues.
  
  
  
  Test the Output:
  
  Once the configuration is corrected, generate the output again to see if the error persists.
  
  
  
  Consult Documentation:
  
  If you are unsure about the correct structure, refer to SAP documentation or guidelines for DMEE configuration to understand the expected hierarchy.
