• What is the cause and solution for SAP error message FL165 - Parameter & is not an export parameter ?

  The SAP error message FL165, which states "Parameter & is not an export parameter," typically occurs in the context of function modules or methods in ABAP (Advanced Business Application Programming). This error indicates that a parameter you are trying to use as an export parameter is not defined as such in the function module or method signature.
  Cause:
  
  Incorrect Parameter Type: The parameter you are trying to use is not defined as an export parameter in the function module or method. It may be defined as an import parameter, changing the way it can be used.
  Typographical Error: There might be a typo in the parameter name when calling the function module or method.
  Misunderstanding of Parameter Roles: The developer may not fully understand the roles of the parameters (import, export, changing, etc.) in the function module or method.
  
  Solution:
  
  
  Check Function Module/Method Definition: 
  
  Go to the function module or method definition in SE37 (for function modules) or SE80 (for classes and methods).
  Verify the parameter list to ensure that the parameter you are trying to use is indeed defined as an export parameter.
  
  
  
  Correct Parameter Usage:
  
  If the parameter is not an export parameter, you need to adjust your code to use it correctly. For example, if it is an import parameter, you should be passing a value to it rather than expecting it to return a value.
  
  
  
  Modify Your Code:
  
  If you mistakenly used the wrong parameter type, modify your code to align with the correct parameter type. For example, if you need to retrieve a value, ensure you are using an export parameter or a changing parameter.
  
  
  
  Consult Documentation: 
  
  If you are unsure about the parameters, refer to the SAP documentation or the function module's documentation to understand its intended use.
