How To Fix WZ174 - The event starts the consumer using an RFC connection

SAP Error Message - Details

• Message type: E = Error

• Message class: WZ - Workflow: Model objects

• Message number: 174

• Message text: The event starts the consumer using an RFC connection

What causes this issue?

The event starts the receiver via an RFC connection. The receiver is
probably defined in a remote system and can therefore not be subjected
to any further checks.
SYSTEM_RESPONSE&

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

You can log on to the remote system and check the receiver (task).

• What is the cause and solution for SAP error message WZ174 - The event starts the consumer using an RFC connection ?

  Certainly! Here's a detailed explanation for the SAP error message WZ174:
  
  SAP Message: WZ174 - The event starts the consumer using an RFC connection
  
  1. Cause
  The message WZ174 typically occurs in the context of SAP Event Management (EM) or Workflow when an event triggers the start of a consumer process via an RFC (Remote Function Call) connection.
  
  The system is trying to start a consumer (a process or program that consumes the event) by calling it remotely using an RFC connection.
  This message is informational and indicates that the event processing mechanism is initiating the consumer through an RFC call.
  It may appear in logs or traces when an event is processed and the consumer is started remotely.
  Sometimes, if the RFC connection is not properly configured or the consumer program is not reachable, this message can be accompanied by errors or failures.
  
  
  2. Solution
  
  
  Check RFC Connection:
  
  Verify that the RFC destination used to start the consumer is correctly configured and active.
  Use transaction SM59 to test the RFC connection.
  
  
  
  Check Consumer Program:
  
  Ensure that the consumer program or workflow is correctly registered and active.
  Verify that the consumer can be started manually or via other means.
  
  
  
  Check Event Configuration:
  
  Review the event linkage and ensure that the event is correctly linked to the consumer.
  Use transaction WE20 (Partner Profiles) or SWETYPV (Event Linkage) depending on the context.
  
  
  
  Check Authorizations:
  
  Ensure that the user under which the RFC call is made has the necessary authorizations to start the consumer.
  
  
  
  Monitor Logs:
  
  Check system logs (SM21), application logs (SLG1), and workflow logs (SWI1) for any related errors or warnings.
  
  
  
  If the message is informational and no error follows:
  
  No action is needed; this message simply informs that the event is starting the consumer via RFC.
  
  
  
  
  3. Related Information
  
  
  Transaction Codes:
  
  SM59 - RFC Destinations

  SAP Notes:
  
  Check SAP Notes related to event management and RFC errors if you encounter failures after this message.
  
  
  
  Context:
  
  This message is common in distributed SAP systems where events trigger processes in different systems or clients.
  It is part of the event-driven architecture in SAP, where events can start workflows or other consumers remotely.
