• What is the cause and solution for SAP error message /CFG/EXP112 - Design Error! Prefix operator &1 assumed to be a Unary operator ?

  The SAP error message /CFG/EXP112 Design Error! Prefix operator &1 assumed to be a Unary operator typically occurs in the context of SAP configuration or development, particularly when dealing with expressions in the context of ABAP or configuration settings.
  Cause:
  This error message indicates that there is a problem with the way an expression is defined in your configuration or code. Specifically, it suggests that a prefix operator (like +, -, !, etc.) is being used incorrectly or is not recognized in the context where it is applied. The system assumes that the operator is intended to be a unary operator, which means it is expected to operate on a single operand rather than a binary operation (which would involve two operands).
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Expression: Review the expression where the error occurs. Ensure that the prefix operator is being used correctly. For example, if you are using a logical operator, make sure it is applied to a valid operand.
  
  
  Correct Syntax: Ensure that the syntax of the expression is correct. If you are using a binary operator, make sure that both operands are present. For example, if you have something like +A, it should be A + B if you are trying to add two variables.
  
  
  Review Documentation: Consult the SAP documentation or help resources for the specific context in which you are working. This can provide insights into the correct usage of operators and expressions.
  
  
  Debugging: If you are unable to identify the issue, consider using debugging tools to step through the code or configuration to see where the error is being triggered.
