This error typically arises in the context of SAP's data processing or reporting functionalities, particularly when dealing with conditions or filters in queries or data models.
  Cause:
  The error occurs when:
  
  An attempt is made to invert a logical operator that does not support inversion. For example, certain operators like IS NULL or IS NOT NULL cannot be inverted in the same way that standard comparison operators (like =, >, <, etc.) can.
  There may be a syntax error in the query or condition being defined, leading to an invalid logical expression.
  The operator being used may not be compatible with the data types involved in the operation.
  
  Solution:
  To resolve this error, consider the following steps:
  
  Review the Logical Expression: Check the logical expression or condition where the error is occurring. Ensure that you are using valid operators that can be inverted.
  Correct Syntax: Make sure that the syntax of your query or condition is correct. Look for any misplaced parentheses or incorrect operator usage.
  Use Compatible Operators: If you are trying to invert a condition, ensure that the operator you are using supports inversion. For example, instead of trying to invert IS NULL, consider using a different approach to achieve the desired logic.
  Check Data Types: Ensure that the data types of the fields being compared are compatible with the operators being used.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on the specific operators and their usage in the context you are working with.
