  SAP Error Message: WER460 *****151 - 169: Method call checks (part 2)
  
  1. Cause
  The error message WER460 with the text "Method call checks (part 2)" typically occurs during the execution of ABAP code when there is an issue related to method calls in object-oriented programming within SAP. This message is part of the runtime checks performed by the SAP kernel or the ABAP runtime environment to ensure the correctness of method invocations.
  Common causes include:
  
  Incorrect method call syntax: Calling a method with wrong parameters or calling a method that does not exist in the class/interface.
  Calling a method on an uninitialized or null object reference: The object reference used to call the method is not instantiated.
  Mismatch between method signature and call: The parameters passed do not match the method's definition.
  Authorization or system checks failing during method execution: Sometimes, internal checks within the method trigger this error.
  Kernel or runtime inconsistencies: Rarely, this can be due to kernel bugs or inconsistencies in the runtime environment.
  
  
  2. Solution
  To resolve the WER460 error, follow these steps:
  
  
  Check the ABAP code where the method is called:
  
  Verify that the object reference is properly instantiated before the method call.
  Ensure the method exists in the class/interface and is accessible (public/protected as required).
  Confirm that the parameters passed to the method match the method signature exactly (type, number, order).
  
  
  
  Debug the program:
  
  Use the ABAP debugger to step through the code and identify the exact point where the error occurs.
  Check the state of the object reference and parameters at runtime.
  
  
  
  Check for Null or Uninitialized Objects:
  
  Make sure the object is created using CREATE OBJECT before calling its methods.
  
  
  
  Review recent changes:
  
  If this error started after a transport or code change, review the changes for method signature or object instantiation issues.
  
  
  
  Check SAP Notes and Kernel Patches:
  
  Search for SAP Notes related to WER460 or method call errors.
  Apply any relevant kernel patches or support packages if the issue is due to a known bug.
  
  
  
  Authorization Checks:
  
  If the method involves authorization checks, ensure the user has the necessary permissions.
  
  
  
  Consult SAP Documentation:
  
  Review the ABAP Object documentation for correct method call practices.
