KH437 - Details

• The SAP error message KH437, which states "User-defined functions can only be used alone," typically occurs in the context of SAP's reporting and analysis tools, particularly when working with user-defined functions in the context of planning or reporting.
  
  Cause:
  This error arises when a user-defined function is being used in conjunction with other functions or calculations in a way that is not permitted. User-defined functions in SAP are designed to perform specific calculations or operations independently, and they cannot be combined with other functions or used as part of a larger expression.
  
  Solution:
  To resolve the KH437 error, you should:
  
  
  Isolate the User-Defined Function: Ensure that the user-defined function is used on its own, without being combined with other functions or calculations. For example, if you have a formula that looks like this:
  = UserDefinedFunction() + AnotherFunction()
  You should separate them:
  = UserDefinedFunction()
  and handle the result of UserDefinedFunction() separately.
  
  
  Check Function Syntax: Review the syntax of the user-defined function
