  Error Message
  WER192 Operator &1 is invalid
  
  &1 is a placeholder for the operator that was found invalid.
  
  
  Cause
  This error occurs when an invalid or unrecognized operator is used in a condition or expression within SAP. Typically, this happens in:
  
  Workflow conditions
  Business rules
  Custom code or user exits
  Selection criteria or filters
  
  The operator provided is not part of the allowed set of operators in the context where it is used.
  
  Common Scenarios
  
  Using an operator that is not supported in the workflow condition editor.
  Typing errors in the operator (e.g., using == instead of =).
  Using operators from other programming languages that SAP does not recognize.
  Incorrect use of logical operators in selection screens or reports.
  
  
  Solution
  
  
  Check the operator used:
  
  Verify the operator in the condition or expression.
  Ensure it is one of the valid operators supported by SAP in that context.
  
  
  
  Use valid operators:
  
  For example, in workflow conditions, valid operators include:
  
  =, <>, <, >, <=, >=
  Logical operators like AND, OR, NOT (used properly)
  
  
  Avoid operators like ==, !=, or others not recognized by SAP.
  
  
  
  Correct the syntax:
  
  If the operator is mistyped, correct it.
  If the operator is invalid for the context, replace it with a valid one.
  
  
  
  Check SAP documentation or help:
  
  Refer to the SAP help for the specific module or tool you are using to confirm valid operators.
  
  
  
  Test the condition after correction:
  
  After fixing the operator, test the workflow or report to ensure the error is resolved.

  SAP Notes: Sometimes, specific SAP Notes address issues with operators in certain modules or versions.
  Workflow Conditions: In SAP Business Workflow, conditions must use valid operators; invalid ones cause this error.
  ABAP Code: In ABAP, operators must follow ABAP syntax; using invalid operators in code or conditions can trigger this error.
  Transaction Codes: Errors can appear in transactions like SWDD (Workflow Builder), SE38 (ABAP Editor), or selection screens.
  
  
  Example
  If you have a workflow condition like:
  Status == 'COMPLETED'

  Status = 'COMPLETED'
