  The SAP error message:
  WFRE_CON204 FRE_SEND_OPTION-Parameter missing! FRE_ACTIVE or FRE_RFC is initial
  
  Cause
  This error occurs in the SAP Workflow Runtime Environment (WFRE) when a function module or workflow container expects the parameter FRE_SEND_OPTION to be filled with either FRE_ACTIVE or FRE_RFC, but both are found to be initial (empty or not set). Essentially, the workflow runtime is trying to send or trigger a workflow task or event, but the communication method or sending option is not specified.
  
  FRE_SEND_OPTION is a structure or parameter that controls how the workflow runtime sends messages or triggers events.
  FRE_ACTIVE and FRE_RFC are flags or parameters within FRE_SEND_OPTION that indicate whether the workflow should be executed actively (synchronously) or via RFC (Remote Function Call).
  If both are initial, the system does not know how to proceed with sending the workflow message.
  
  
  When does it happen?
  
  When triggering workflows programmatically or via function modules like SAP_WAPI_CREATE_EVENT or SAP_WAPI_START_WORKFLOW.
  When custom code or enhancements call
