• What is the cause and solution for SAP error message S_UNIFIED_CON021 - Function module &1 is does not exist or is not remote-enabled ?

  The SAP error message S_UNIFIED_CON021 indicates that a function module you are trying to call does not exist or is not remote-enabled. This error typically occurs in scenarios where you are attempting to execute a remote function call (RFC) to a function module that is either not defined in the system or is not set up to be called remotely.
  Causes:
  
  Function Module Does Not Exist: The function module you are trying to call may not be created or may have been deleted.
  Incorrect Function Module Name: There may be a typo or incorrect naming in the function module name you are trying to call.
  Not Remote-Enabled: The function module exists but is not marked as remote-enabled. This means it cannot be called from another system or via RFC.
  Authorization Issues: The user or system trying to call the function module may not have the necessary authorizations to access it.
  Transport Issues: If the function module was recently transported from another system, it may not have been activated properly.
  
  Solutions:
  
  
  Check Function Module Existence:
  
  Go to transaction code SE37 (Function Builder) and check if the function module exists.
  Ensure that the name is spelled correctly.
  
  
  
  Check Remote-Enabled Status:
  
  In the function module definition, check if the "Remote-Enabled Module" checkbox is selected. If it is not, you will need to enable it.
  If you do not have the necessary authorizations to change this, contact your SAP administrator.
  
  
  
  Authorization Check:
  
  Ensure that the user or system making the RFC call has the necessary authorizations to execute the function module. You can check this using transaction SU53 after the error occurs.
  
  
  
  Activation:
  
  If the function module was recently transported, ensure that it has been activated in the target system. You can do this in SE37 by checking the activation status.
  
  
  
  Check for Typos:
  
  Double-check the code or configuration where the function module is being called to ensure there are no typographical errors.
