SAP Error Message - Details

• Message type: E = Error

• Message class: DMEE_ABA - Messages for Data Medium Exchange Engine

• Message number: 337

• Message text: Node &1: aggregation not permitted using node &2

What causes this issue?

In the aggregation data for node &V1&, aggregation is defined via node
&V2& (by means of reference ID &V3&). This aggregation is not possible
for one of the following reasons:
Node &V2& has a lower level than node &V1&
Both nodes have the same level, but are in different segments, and the
segment which contains node &V2& is not an optional supplementary
segment of the segment that contains node &V1&

• What is the cause and solution for SAP error message DMEE_ABA337 - Node &1: aggregation not permitted using node &2 ?

  The SAP error message DMEE_ABA337 typically occurs in the context of the Data Medium Exchange Engine (DMEE) when you are trying to generate a payment medium file, particularly in the context of bank transfers or similar financial transactions. This error indicates that there is an issue with the aggregation settings in your DMEE tree structure.
  Cause:
  The error message "aggregation not permitted using node &2" suggests that there is an attempt to aggregate data in a way that is not allowed for the specified node. This can happen due to several reasons:
  
  
  Incorrect Node Configuration: The node that you are trying to aggregate may not be configured to allow aggregation. This can happen if the node is set up to handle individual records rather than aggregated data.
  
  
  Hierarchy Issues: The structure of the DMEE tree may not support the type of aggregation you are trying to perform. For example, if you are trying to aggregate payment items that are not compatible with the parent node's settings.
  
  
  Data Structure Mismatch: The data being processed may not match the expected structure defined in the DMEE tree, leading to aggregation errors.
  
  
  Solution:
  To resolve the DMEE_ABA337 error, you can take the following steps:
  
  
  Check Node Configuration:
  
  Open the DMEE tree in transaction code DMEE.
  Review the properties of the nodes involved (the node where the error occurs and the node being aggregated).
  Ensure that the aggregation settings are correctly configured. If a node is not meant to aggregate data, ensure that it is not being used in an aggregation context.
  
  
  
  Review Aggregation Logic:
  
  Ensure that the aggregation logic you are trying to implement is valid for the nodes involved. If necessary, adjust the tree structure to accommodate the required aggregation.
  
  
  
  Test with Sample Data:
  
  Run a test with a smaller set of data to see if the error persists. This can help isolate whether the issue is with specific data records.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for guidance on configuring DMEE trees and understanding aggregation rules.
  
  
  
  Debugging:
  
  If you have access to debugging tools, you can trace the execution to see where the aggregation is failing and gather more context about the error.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. Provide them with the details of the error and the configuration you are using.
