• What is the cause and solution for SAP error message EZ800 - Internal error: Parameter &1 was not supplied in FM &2 ?

  The SAP error message EZ800, which states "Internal error: Parameter &1 was not supplied in FM &2," typically indicates that a function module (FM) is being called without providing all the required parameters. This can occur in various scenarios, such as when a program or a function module is executed, and it expects certain input parameters that are not being passed correctly.
  Cause:
  
  Missing Parameters: The most common cause is that the function module is defined with certain parameters that are mandatory, but the calling program does not supply them.
  Incorrect Function Module Call: The function module might be called incorrectly, either due to a typo in the parameter name or by not following the expected interface.
  Changes in Function Module: If the function module has been modified (e.g., parameters added or changed) and the calling program has not been updated accordingly, this error can occur.
  Dynamic Calls: If the function module is called dynamically (e.g., using CALL FUNCTION with a variable name), it may not be able to resolve the parameters correctly.
  
  Solution:
  
  Check Function Module Definition: Go to transaction SE37 (Function Builder) and check the definition of the function module mentioned in the error message. Verify which parameters are required and ensure they are being supplied in the calling program.
  Update Calling Program: If parameters are missing, update the calling program to include the necessary parameters when calling the function module.
  Review Changes: If the function module has been recently changed, review the changes and ensure that all calling programs are updated to match the new interface.
  Debugging: Use the debugger to step through the code where the function module is called. This can help identify which parameters are not being passed correctly.
  Check for Dynamic Calls: If the function module is being called dynamically, ensure that the parameters are being passed correctly and that the variable names match the expected parameter names.
