• What is the cause and solution for SAP error message FL164 - Parameter & is not an import parameter ?

  The SAP error message FL164, which states "Parameter & is not an import parameter," typically occurs in the context of function modules or BAPIs (Business Application Programming Interfaces) when there is an issue with the parameters being passed to a function.
  Cause:
  
  
  Incorrect Parameter Type: The parameter being passed to the function module is not defined as an import parameter in the function's interface. This can happen if:
  
  The parameter name is misspelled.
  The parameter is not included in the function module's definition.
  The parameter is mistakenly treated as an import parameter when it is actually an export or changing parameter.
  
  
  
  Function Module Changes: If the function module has been modified (e.g., by an upgrade or a custom implementation), the parameters may have changed, leading to this error.
  
  
  Calling Convention: The way the function module is being called may not match the expected calling convention, leading to mismatches in parameter types.
  
  
  Solution:
  
  
  Check Function Module Definition: 
  
  Go to transaction SE37 (Function Module) or SE80 (Object Navigator) and check the definition of the function module you are calling.
  Verify that the parameter you are trying to pass is indeed defined as an import parameter.
  
  
  
  Correct Parameter Name: 
  
  Ensure that the parameter name you are using in your code matches exactly with the name defined in the function module. Pay attention to case sensitivity and spelling.
  
  
  
  Review Parameter Types: 
  
  Make sure you are passing the correct data type and structure that the function module expects for the import parameter.
  
  
  
  Check for Changes: 
  
  If the function module has been modified, check the change logs or documentation to understand what changes were made and how they affect the parameters.
  
  
  
  Debugging: 
  
  If you are still facing issues, consider using the debugger to step through the code and see what parameters are being passed at runtime.
  
  
  
  Related Information:
  
  Function Module Documentation: Always refer to the documentation of the function module for detailed information about its parameters and expected input.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific function module you are using.
  Community Forums: If you are unable to resolve the issue, consider reaching out to SAP community forums or support for additional assistance.
