  The called function module or method does not exist or is not active.
  Authorization issues preventing the execution of the function/method.
  Incorrect parameters passed to the function/method.
  Runtime errors inside the function module or method (e.g., division by zero, database errors).
  Communication or interface problems if the function module is remote (RFC).
  Missing or inconsistent data required by the function/method.
  
  
  Solution / Troubleshooting Steps
  
  
  Check the exact function module or method name
  
  Identify the function module or method name from the error message (replaces &1).
  
  
  Check the function module/method existence and activation  
  
  Use transaction SE37 (Function Builder) to check if the function module exists and is active.  
  For methods, check the class in SE24 and verify the method.
  
  
  
  Check the parameters passed  
  
  Review the calling program or transaction to ensure the parameters passed to the function/method are correct and complete.  
  Debug the program to see the exact call and parameter values.
  
  
  
  Check authorizations  
  
  Verify if the user has the necessary authorizations to execute the function module or method.
  
  
  
  Debug the function module/method  
  
  Set breakpoints in the function module or method and reproduce the error to find the exact cause.  
  Look for runtime errors or exceptions inside the function/method.
  
  
  
  Check system logs and dumps  
  
  Use transaction ST22 to check for short dumps related to the error.  
  Use transaction SM21 to check system logs for related errors.
  
  
  
  Check RFC connections (if applicable)  
  
  If the function module is called remotely, verify the RFC destination and connection status in SM59.
  
  
  
  Check OSS Notes and SAP Support
