• What is the cause and solution for SAP error message DMEE555 - Node &1, condition step &2: '!' enter only in front of '(' ?

  Cause:
  The error message DMEE555 occurs when the logical operator ! is used incorrectly in the condition step of the DMEE tree. In SAP DMEE, the ! operator should only be placed directly in front of a parenthesis ( when negating a condition. If it is placed elsewhere or used incorrectly, the system will throw this error.
  Solution:

  Check the Condition Step: Go to the DMEE tree where the error is reported. Look for the specific node and condition step mentioned in the error message (Node &1, Condition Step &2).
  
  
  Correct the Syntax: Ensure that the ! operator is only used directly in front of a parenthesis. For example, if you have a condition like ! (A = B), that is correct. However, if you have something like A ! = B or ! A = B, it will cause the error.
  
  
  Review Other Conditions: Check other conditions in the same node or related nodes to ensure that they follow the correct syntax as well.
  
  
  Test the Configuration: After making the necessary corrections, save the changes and test the DMEE configuration to ensure that the error no longer appears.
  
  
  Documentation and Help: If you are unsure about the correct syntax or need further assistance, refer to the SAP documentation on DMEE or consult with a colleague who has experience with DMEE configurations.
