  The SAP error message DMEE090, which states "Node &1 is deactivated in child tree," typically occurs in the context of the Data Medium Exchange Engine (DMEE) when generating payment files or other data formats. This error indicates that a specific node in the DMEE tree structure is deactivated, which prevents the system from processing the data correctly.
  Cause:
  
  Node Deactivation: The specific node referenced in the error message is deactivated in the DMEE tree structure. This can happen if the node was intentionally deactivated by a user or if there was a configuration change that affected the node's status.
  Incorrect Configuration: The DMEE tree may not be configured correctly, leading to certain nodes being inactive when they should be active.
  Hierarchy Issues: The structure of the DMEE tree may have issues, such as missing parent nodes or incorrect relationships between nodes.
  
  Solution:
  
  
  Activate the Node:
  
  Go to the DMEE tree configuration (transaction code DMEE).
  Locate the node indicated in the error message.
  Check the status of the node and activate it if it is deactivated. You can do this by selecting the node and changing its status to active.
  
  
  
  Review the DMEE Tree Structure:
  
  Ensure that the hierarchy of the DMEE tree is correct. Check for any missing nodes or incorrect configurations that might lead to deactivation.
  Validate that all necessary parent nodes are active and correctly configured.
  
  
  
  Check for Dependencies:
  
  Some nodes may depend on other nodes being active. Ensure that all related nodes are properly activated and configured.
  
  
  
  Test the Configuration:
  
  After making changes, test the DMEE configuration to ensure that the error does not occur again. You can do this by generating a test file or running a simulation.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration or the purpose of the node, refer to the SAP documentation or consult with a colleague who has experience with DMEE configurations.
