How To Fix DMEE337 - Node &1: aggregation not permitted using node &2

SAP Error Message - Details

• Message type: E = Error

• Message class: DMEE - 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 DMEE337 - Node &1: aggregation not permitted using node &2 ?

  The SAP error message DMEE337 indicates that there is an issue with the aggregation of nodes in the Data Medium Exchange Engine (DMEE) configuration. Specifically, it means that the system is trying to aggregate data in a way that is not permitted for the specified nodes.
  Cause:
  The error typically arises when:
  
  Incorrect Node Configuration: The nodes involved in the aggregation are not set up correctly. For example, you might be trying to aggregate data from a node that is not designed to be aggregated.
  Hierarchy Issues: The structure of the DMEE tree may not support the aggregation you are attempting. Certain nodes may be defined as leaf nodes and cannot be aggregated.
  Data Structure Violations: The data being processed may not conform to the expected structure, leading to aggregation attempts on incompatible nodes.
  
  Solution:
  To resolve the DMEE337 error, you can take the following steps:
  
  
  Check Node Configuration:
  
  Review the configuration of the nodes involved in the aggregation. Ensure that the nodes are set up correctly and that the aggregation is permitted for those nodes.
  Verify the properties of the nodes in the DMEE tree to ensure they are compatible with aggregation.
  
  
  
  Review the DMEE Tree Structure:
  
  Examine the hierarchy of the DMEE tree. Make sure that the nodes you are trying to aggregate are at the correct level and that their relationships are properly defined.
  If necessary, adjust the structure of the DMEE tree to allow for the desired aggregation.
  
  
  
  Adjust Aggregation Settings:
  
  If you are using specific aggregation functions, ensure that they are appropriate for the nodes in question. You may need to change the aggregation method or the nodes being aggregated.
  
  
  
  Test with Sample Data:
  
  Run tests with sample data to see if the error persists. This can help identify if the issue is with the data being processed or the configuration itself.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed information on DMEE configuration and node aggregation rules.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists after checking the configuration and structure, consider reaching out to SAP support for further assistance.
  
  
  
  Related Information:
  
  DMEE Configuration: Understanding how to configure DMEE trees and nodes is crucial for resolving this error. Familiarize yourself with the DMEE transaction codes (e.g., DMEE) and the relevant documentation.
  Aggregation Functions: Learn about the different aggregation functions available in DMEE and their appropriate use cases.
  Error Logs: Check the application logs for additional context or related error messages that may provide more insight into the issue.
  
  By following these steps, you should be able to identify and resolve the cause of the DMEE337 error in your SAP system.
