• What is the cause and solution for SAP error message DMEE329 - Error in node &1: reference ID &2 not permitted in aggregation ?

  The SAP error message DMEE329 indicates that there is an issue with the configuration of the Data Medium Exchange Engine (DMEE) in SAP, specifically related to the aggregation of nodes in the DMEE tree structure. This error typically occurs when a reference ID is used in a way that is not permitted during the aggregation process.
  Cause:
  The error message DMEE329 is triggered when:
  
  A node in the DMEE tree is trying to aggregate data using a reference ID that is not allowed for that specific node.
  The configuration of the DMEE tree may have inconsistencies or incorrect settings that lead to this error.
  The reference ID used in the aggregation does not match the expected format or type for the node.
  
  Solution:
  To resolve the DMEE329 error, you can follow these steps:
  
  
  Check DMEE Configuration:
  
  Go to the DMEE transaction (transaction code: DMEE).
  Review the configuration of the DMEE tree structure, focusing on the node that is causing the error.
  Ensure that the reference IDs used in the aggregation are correctly defined and permitted for that node.
  
  
  
  Review Aggregation Settings:
  
  Check the aggregation settings for the node in question. Make sure that the reference ID is appropriate for the type of aggregation being performed.
  If necessary, modify the aggregation settings to use a valid reference ID.
  
  
  
  Validate Node Properties:
  
  Ensure that the properties of the node (such as the type of data it is supposed to handle) are correctly set.
  If the node is supposed to aggregate data from multiple sources, ensure that all source nodes are correctly configured.
  
  
  
  Test the Configuration:
  
  After making changes, test the DMEE configuration to see if the error persists.
  Use the "Test" functionality in the DMEE transaction to simulate the output and check for any further errors.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on configuring DMEE nodes and handling reference IDs.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists after checking the configuration, consider reaching out to SAP support for further assistance.
