• What is the cause and solution for SAP error message WER163 - Error occurred during dynamic method call ?

  Certainly! Here's a detailed explanation regarding the SAP error message WER163: Error occurred during dynamic method call:
  
  Error Message:
  WER163 - Error occurred during dynamic method call
  
  Cause:
  This error typically occurs when an ABAP program or SAP standard process tries to dynamically call a method (using CALL METHOD or similar dynamic invocation techniques), but the method call fails. The failure can be due to several reasons, such as:
  
  The method name being called dynamically does not exist or is misspelled.
  The class or object reference on which the method is called is NULL or not properly instantiated.
  The method signature does not match the parameters passed dynamically.
  Authorization or runtime errors inside the method being called.
  The dynamic call is made on an interface or class that does not implement the method.
  Issues with the underlying business object or framework (e.g., Business Object Repository (BOR), Workflow, or other dynamic method calls in SAP).
  
  
  Typical Scenarios:
  
  Dynamic method calls in BOR (Business Object Repository) or Workflow.
  Dynamic calls in custom ABAP code using CALL METHOD (lv_method) where lv_method is a variable.
  Calls to methods in classes generated or used dynamically.
  Errors in SAP standard transactions or reports that use dynamic method calls.
  
  
  Solution / Troubleshooting Steps:
  
  
  Check the Method Name:
  
  Verify that the method name being called dynamically is correct.
  Check for typos or case sensitivity issues.
  
  
  
  Check Object Instantiation:
  
  Ensure the object reference on which the method is called is properly instantiated and not NULL.
  Use debugging to check the object reference before the dynamic call.
  
  
  
  Check Method Signature:
  
  Verify that the parameters passed to the method match the method’s signature.
  Check for missing or extra parameters.
  
  
  
  Debug the Dynamic Call:
  
  Set a breakpoint before the dynamic method call.
  Inspect the method name, object reference, and parameters.
  Step into the method call to see if the error occurs inside the method.
  
  
  
  Check Authorizations:
  
  Sometimes, the method might fail due to missing authorizations.
  Check if the user has the necessary permissions.
  
  
  
  Check for SAP Notes:
  
  Search for SAP Notes related to WER163 or the specific transaction/module you are working with.
  SAP Notes might provide patches or workarounds.
  
  
  
  Review Custom Code:
  
  If the error occurs in custom code, review the dynamic method call logic.
  Consider replacing dynamic calls with static calls if possible for better error handling.
  
  
  
  Check Business Object Repository (BOR) / Workflow:
  
  If the error occurs in BOR or Workflow, check the BOR object and method definitions.
  Ensure the method exists and is active.
  Check for inconsistencies in BOR or Workflow configuration.
  
  
  
  
  Related Information:
  
  
  Transaction / Tools:
  
  Use SE24 to check class and method definitions.
  Use SE80 or SE37 to check function modules or classes.
  Use SWO1 to check BOR objects.
  Use SWDD to check workflows.
  
  
  
  Common ABAP Statements Involved:
  
  CALL METHOD (lv_method) OF obj_ref
  CALL METHOD (lv_method)
  
  
  
  SAP Notes Examples:
  
  Search SAP Support Portal for notes with keywords: WER163, dynamic method call error, BOR dynamic method call.
  
  
  
  Debugging Tips:
  
  Use the debugger to inspect the dynamic method call.
  Check the call stack to identify where the error occurs.
  Use BREAK-POINT or BREAK <method_name> to catch the error inside the method.
