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

DMEE337 - Overview

• 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&

DMEE337 - Details

• 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.
