• What is the cause and solution for SAP error message WY125 - FM &. Too many parameters ?

  SAP Error Message:
  
  WY125 FM &. Too many parameters
  
  Cause:
  The error message WY125 with the text "Too many parameters" typically occurs in SAP Funds Management (FM) when a function module (FM) or a report is called with more parameters than it is designed to handle. This can happen due to:
  
  Incorrect or outdated custom code calling a standard FM with an incorrect number of parameters.
  A mismatch between the interface of the FM and the parameters passed.
  A user exit, BAdI, or enhancement implementation passing extra parameters.
  A transport or system upgrade issue where the FM interface has changed but the calling program has not been adjusted accordingly.
  
  
  Explanation:
  In SAP, function modules have a defined interface specifying the number and type of parameters they accept. If a program calls a function module with more parameters than defined, the system raises the WY125 error to prevent runtime inconsistencies.
  
  Solution:
  
  
  Check the Function Module Call:
  
  Identify the function module mentioned in the error message (the placeholder "&" in WY125 FM & will be replaced by the FM name in the actual message).
  Review the code where this FM is called.
  Compare the number and type of parameters passed in the call with the FM's interface in transaction SE37.
  
  
  
  Correct the Parameter List:
  
  Adjust the calling program to pass only the parameters defined in the FM interface.
  Remove any extra parameters or adjust the code logic accordingly.
  
  
  
  Check for Custom Enhancements:
  
  If the FM is called inside a user exit, BAdI, or enhancement spot, verify that the custom code is updated and consistent with the FM interface.
  
  
  
  Check for System or Transport Issues:
  
  If the FM interface was changed due to a system upgrade or patch, ensure that all dependent custom code is updated.
  Re-import transports if necessary.
  
  
  
  Debugging:
  
  Use the ABAP debugger to trace the call stack and identify where the extra parameters are being passed.
  This helps pinpoint the exact location in the code causing the issue.

  Summary:
  
  Cause: Calling a function module with more parameters than defined.
  Solution: Adjust the calling program to match the FM interface parameters.
  Check: FM interface in SE37, calling code, custom enhancements, and system upgrade impacts.
