  The SAP error message DMEE360 typically occurs in the context of the Data Medium Exchange Engine (DMEE) when there is an issue with the aggregation settings for a specific node in the DMEE tree structure. This error indicates that the system is unable to perform an aggregation operation for a node due to the specified aggregation type.
  Cause:
  The error message "Node &1: aggregation with aggregation type 2 not possible for node &2" suggests that:
  
  Aggregation Type: The aggregation type specified for the node is not compatible with the data being processed. Aggregation type 2 usually refers to a specific method of summing or combining values.
  Node Configuration: The configuration of the node may not support the aggregation type being used. This could be due to the node's properties or the data structure.
  Data Issues: There may be no data available for aggregation, or the data does not meet the criteria required for the aggregation type.
  
  Solution:
  To resolve the DMEE360 error, you can take the following steps:
  
  
  Check Node Configuration:
  
  Review the configuration of the node mentioned in the error message. Ensure that the aggregation type is appropriate for the data being processed.
  Verify that the node is set up to allow aggregation. If necessary, adjust the properties of the node to support the desired aggregation type.
