Resolution

The agent requires an ABAP connection no matter what which is why it's complaining about the ABAP stack.  It can point to a different system even, but it must have an ABAP connection as well as the PI/XI connection.

1. Log into client 0 as an admin user
2. Create an R3 Connection object with Connection Type Remote Function Call, fill in information and save the object
3. Go to the Administration perspective and to Agents & Agentgroups
4. Double-click on the agent to open the definition
5. Assign the connection object from step 2 above to the SAP System connection
   
6. Save the agent definition and start the agent
