  The SAP error message DMEE550 typically occurs in the context of the Data Medium Exchange Engine (DMEE) when there is an issue with the configuration of the DMEE tree structure. This error indicates that there is a problem with a condition defined for a specific node in the DMEE tree, specifically that the node is trying to reference another node that is not allowed or does not exist.
  Cause:
  
  Invalid Node Reference: The error suggests that the condition for the specified node (&1) is trying to refer to another node (&3) that is either not defined or not valid in the context of the current node.
  Incorrect Condition Logic: The logic defined in the condition may be incorrect, leading to an invalid reference.
  Hierarchy Issues: The structure of the DMEE tree may not be set up correctly, causing nodes to be improperly referenced.
  
  Solution:
  
  Check Node Definitions: Verify that the node you are trying to reference (&3) is correctly defined in the DMEE tree. Ensure that it exists and is accessible from the node where the condition is being applied.
  Review Condition Logic: Examine the condition logic for the node (&1). Ensure that it is correctly formulated and does not reference nodes that are not allowed or do not exist.
  Adjust Hierarchy: If the node structure is incorrect, you may need to adjust the hierarchy of the DMEE tree to ensure that nodes are properly related and can reference each other as intended.
  Testing: After making changes, test the DMEE configuration to ensure that the error is resolved and that the output is as expected.
