• What is the cause and solution for SAP error message DMEE392 - Error in checks for node &1: inadmissible operator in line &2 ?

  The SAP error message DMEE392 indicates that there is an issue with the configuration of the Data Medium Exchange Engine (DMEE) in SAP. Specifically, it points to an "inadmissible operator" being used in a certain line of the DMEE tree structure. This error typically arises when the DMEE tree is not correctly defined, leading to invalid expressions or operators being used.
  Cause:
  
  Invalid Operators: The error is often caused by using operators in the DMEE tree that are not allowed or are incorrectly applied. This could be due to syntax errors or logical errors in the configuration.
  Incorrect Node Configuration: The node specified in the error message may have been configured incorrectly, leading to the use of an operator that is not valid for that context.
  Version Compatibility: Sometimes, the version of SAP or the DMEE configuration may not support certain operators or functions.
  
  Solution:
  
  
  Check the DMEE Tree Configuration:
  
  Go to the DMEE transaction (usually transaction code DMEE).
  Open the relevant DMEE tree and navigate to the node specified in the error message.
  Review the configuration of that node, especially the operators used in the expressions.
  
  
  
  Correct the Operators:
  
  Ensure that the operators used are valid for the context of the node. Refer to the DMEE documentation for a list of admissible operators.
  If you find any invalid operators, replace them with the correct ones.
  
  
  
  Validate the Tree:
  
  After making changes, validate the DMEE tree to check for any other potential errors.
  Use the "Check" function in the DMEE transaction to ensure that there are no further issues.
  
  
  
  Test the Configuration:
  
  Once corrections are made, test the DMEE output to ensure that the changes have resolved the issue and that the output is generated as expected.
  
  
  
  Consult Documentation:
  
  If you are unsure about the operators or the configuration, refer to the SAP Help documentation or the DMEE configuration guide for detailed information.
