How To Fix ICL520 - Function module &3: &1 parameters expected, but &2 parameters transferred

SAP Error Message - Details

• Message type: E = Error

• Message class: ICL - FS-CM: Claims Management

• Message number: 520

• Message text: Function module &3: &1 parameters expected, but &2 parameters transferred

What causes this issue?

When the &V3& function module is called during a value request, the
system expects that &V1& parameters are transferred. However, only &V2&
parameters were transferred.

System Response

In view of this inconsistency, the system cancels the process.

How to fix this error?

You must determine which value request is based on the &V3& function
module.
You must check the value request to verify that the number of
transferred parameters matches the number of expected parameters. If n
ecessary, analyze the source code of the &V3& function module.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message ICL520 - Function module &3: &1 parameters expected, but &2 parameters transferred ?

  The SAP error message ICL520 indicates a mismatch in the number of parameters expected by a function module and the number of parameters that were actually transferred when the function was called. This can occur in various scenarios, such as when calling a custom or standard function module in ABAP.
  Cause:
  
  Parameter Mismatch: The function module is defined to accept a certain number of parameters, but the calling program is passing a different number of parameters.
  Incorrect Function Call: The function module might be called incorrectly, either by missing parameters or by providing extra parameters.
  Changes in Function Module: If the function module has been modified (e.g., parameters added or removed) and the calling program has not been updated accordingly, this error can occur.
  Versioning Issues: If there are different versions of the function module in different environments (e.g., development vs. production), this can lead to discrepancies.
  
  Solution:
  
  Check Function Module Definition: Go to transaction SE37 (Function Builder) and check the definition of the function module in question. Verify the number and types of parameters it expects.
  Review Calling Code: Look at the ABAP code where the function module is called. Ensure that the number of parameters being passed matches the expected parameters in the function module.
  Update Code: If the function module has been changed, update the calling program to match the new definition. This may involve adding or removing parameters as necessary.
  Testing: After making changes, test the function call to ensure that it works correctly without errors.
  Documentation: If the function module is part of a standard SAP package, check the SAP notes or documentation for any changes or updates that might affect the function module.
  
  Related Information:
  
  Transaction Codes: 
  
  SE37: Function Module Builder
  SE80: Object Navigator (to find where the function module is used)
  
  
  Debugging: Use the ABAP debugger to step through the code and see the parameters being passed at runtime.
  SAP Notes: Check for any relevant SAP Notes that might address known issues with the function module.
  Version Control: If you are working in a team, ensure that everyone is aware of changes to function modules and that version control practices are followed.
  
  By following these steps, you should be able to identify the cause of the ICL520 error and implement a solution to resolve it.
