• What is the cause and solution for SAP error message EM187 - Function module &1 does not exist ?

  The SAP error message EM187, which states "Function module &1 does not exist," typically indicates that the system is trying to call a function module that is not available in the SAP system. This can happen for several reasons:
  Causes:
  
  Function Module Not Created: The function module may not have been created or activated in the system.
  Incorrect Name: There may be a typo or incorrect name in the code where the function module is being called.
  Transport Issues: If the function module was recently transported from another system, it may not have been transported correctly or may not exist in the target system.
  Authorization Issues: The user may not have the necessary authorizations to access the function module, leading to the perception that it does not exist.
  Namespace Issues: The function module might be in a different namespace that is not accessible in the current context.
  
  Solutions:
  
  
  Check Function Module Existence:
  
  Use transaction code SE37 (Function Builder) to check if the function module exists. Enter the name of the function module and see if it is available.
  
  
  
  Correct the Name:
  
  Verify the spelling and ensure that the function module name is correct in the code where it is being called.
  
  
  
  Transport Check:
  
  If the function module was supposed to be transported, check the transport logs to ensure it was successfully imported into the target system.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to execute the function module. You can check this using transaction SU53 after the error occurs.
  
  
  
  Namespace Verification:
  
  If the function module is in a different namespace, ensure that the calling program has access to that namespace.
  
  
  
  Recreate the Function Module:
