• What is the cause and solution for SAP error message DMEE699 - Node &1: No key field is assigned to level &2 ?

  The SAP error message DMEE699 indicates that there is an issue with the Data Medium Exchange Engine (DMEE) configuration, specifically related to the key fields assigned to a node in the DMEE tree structure. This error typically arises when a node in the DMEE structure does not have a key field assigned, which is necessary for the proper generation of the data medium file.
  Cause:
  
  Missing Key Field Assignment: The node specified in the error message does not have a key field assigned. Key fields are essential for identifying records uniquely in the output file.
  Incorrect Configuration: The DMEE tree structure may not be configured correctly, leading to nodes that are not properly defined.
  Hierarchy Issues: The hierarchy of nodes may be incorrect, causing the system to expect a key field where none is defined.
  
  Solution:
  
  
  Check DMEE Configuration:
  
  Go to the DMEE transaction (transaction code: DMEE).
  Open the relevant DMEE tree structure.
  Navigate to the node indicated in the error message (Node &1).
  Ensure that a key field is assigned to the level indicated (Level &2). You can do this by selecting the node and checking the properties or settings.
  
  
  
  Assign Key Fields:
  
  If no key field is assigned, you need to assign an appropriate key field that corresponds to the data you are processing. This could be a field from the data structure that uniquely identifies records.
  
  
  
  Validate Hierarchy:
  
  Ensure that the hierarchy of nodes is correct and that all necessary nodes have the required key fields assigned. This may involve reviewing parent-child relationships in the DMEE tree.
  
  
  
  Test the Configuration:
  
  After making changes, test the DMEE configuration by generating the data medium file again to ensure that the error is resolved.
  
  
  
  Consult Documentation:
  
  If you are unsure about which key fields to assign, refer to SAP documentation or consult with a colleague who has experience with DMEE configurations.
