  The SAP error message VC2OD_DMT_ASSIST018 indicates that there is a double negation in the expression you are trying to use in a variant configuration context. This typically occurs when you have a logical expression that uses the NOT operator twice on the same condition, which is not allowed in the syntax of the configuration.
  
  Cause:

  Solution:
  To resolve this error, you need to review the logical expressions in your variant configuration and eliminate any instances of double negation. Here are the steps you can take:
  
  
  Identify the Expression: Locate the specific condition or expression that is causing the error. This will usually be in the configuration settings where you define dependencies or constraints.
