How To Fix DMEE_PAYMFORMAT337 - Node &1: aggregation not permitted using node &2

SAP Error Message - Details

• Message type: E = Error

• Message class: DMEE_PAYMFORMAT - Messages for DMEE Payment Formats

• 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 permitted
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 that 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_PAYMFORMAT337 - Node &1: aggregation not permitted using node &2 ?

  The SAP error message DMEE_PAYMFORMAT337 typically occurs in the context of the Data Medium Exchange Engine (DMEE) when there is an issue with the aggregation of nodes in a payment format. This error indicates that the system is trying to aggregate data from one node (Node &2) into another node (Node &1), but the aggregation is not permitted due to the configuration or structure of the DMEE tree.
  Cause:
  
  Incorrect Node Configuration: The nodes involved may not be configured to allow aggregation. This can happen if the node that is being aggregated into (Node &1) does not support the type of data being aggregated from Node &2.
  Hierarchy Issues: The structure of the DMEE tree may not allow for the aggregation of certain nodes due to their hierarchical relationship.
  Data Type Mismatch: The data types of the nodes may not be compatible for aggregation.
  Missing Aggregation Rules: There may be no defined rules for how to aggregate the data from Node &2 into Node &1.
  
  Solution:
  
  Check Node Configuration: Review the configuration of both nodes in the DMEE tree. Ensure that Node &1 is set up to accept aggregated data from Node &2.
  Review Hierarchical Structure: Ensure that the hierarchical structure of the DMEE tree allows for the aggregation. You may need to adjust the tree structure to permit the aggregation.
  Define Aggregation Rules: If necessary, define specific aggregation rules for how data should be combined from Node &2 into Node &1.
  Data Type Compatibility: Ensure that the data types of the nodes are compatible for aggregation. If they are not, you may need to convert or adjust the data types accordingly.
  Consult Documentation: Refer to SAP documentation or the DMEE configuration guide for more detailed information on node aggregation and configuration.
  
  Related Information:
  
  DMEE Configuration: Familiarize yourself with the DMEE configuration settings and how to set up nodes and their properties.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance.
  Testing: After making changes, test the payment format to ensure that the error is resolved and that the output is as expected.
  Support: If the issue persists, consider reaching out to SAP support or consulting with a technical expert who specializes in DMEE configurations.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
