• What is the cause and solution for SAP error message DMEE328 - Error aggregating node &1: aggregation type is inconsistent ?

  The SAP error message DMEE328 indicates that there is an issue with the aggregation type defined for a node in the Data Medium Exchange (DMEE) configuration. This error typically arises when the aggregation settings for a node are inconsistent or not properly defined, which prevents the system from correctly aggregating data for that node.
  Cause:
  
  Inconsistent Aggregation Type: The aggregation type specified for the node does not match the expected type for the data being processed. For example, if a node is set to aggregate data but the data does not support aggregation, this error can occur.
  Incorrect Configuration: The DMEE tree structure may have been incorrectly configured, leading to mismatches in the aggregation settings.
  Missing or Incorrect Node Settings: If a node is expected to aggregate data but lacks the necessary settings or has conflicting settings, this can trigger the error.
  
  Solution:
  
  
  Check Node Configuration:
  
  Go to the DMEE tree structure in the SAP system.
  Review the configuration of the node that is causing the error. Ensure that the aggregation type is correctly set according to the data being processed.
  Make sure that the aggregation type is appropriate for the data structure and the intended output.
  
  
  
  Adjust Aggregation Settings:
  
  If the node is intended to aggregate data, ensure that the aggregation type is set to a valid option (e.g., SUM, COUNT, etc.).
  If the node should not aggregate data, change the aggregation type to "None" or the appropriate setting.
  
  
  
  Validate the DMEE Tree:
  
  Use the DMEE transaction (e.g., DMEE) to validate the entire tree structure for any inconsistencies or errors.
  Make necessary adjustments to ensure that all nodes are correctly configured.
  
  
  
  Test the Configuration:
  
  After making changes, test the DMEE configuration to ensure that the error no longer occurs and that the output is as expected.
  
  
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like DMEE to access the DMEE configuration and make necessary changes.
  Documentation: Refer to SAP documentation or help resources for detailed information on DMEE configuration and aggregation types.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to DMEE328 or provide additional guidance on configuration best practices.
  
  By following these steps, you should be able to resolve the DMEE328 error and ensure that your DMEE configuration is functioning correctly.
