Agent Not Found for rule 168 in Travel Management WF WS20000040

Question

Hi,
I got a strange error occurring that I can not quite figure out. I am using a copy of a standard delivered SAP Work flow for Trip Approval (WS20000040) that is identical to the SAP delivered workflow except without the expense department tasks (we only need manager approval). I also updated the agent assignment for tasks TS20000131, TS20000139, and TS20000189 to be General Tasks. When an employee creates a trip, the workflow is started properly and goes to the first workflow step which is user decision step 416. It uses rule 168 to determine the manager of the workflow initiator. This works properly. The manager goes to their inbox and executes this workflow step. The trip changed and trip approved buttons work fine, but if the manager chooses the reject button, the form is closed and the workflow stops with an error. The next step down the reject path is an activity step 476 - enter and send message. This runs task TS20000139. The agent assignment also uses rule 168 to determine the manager of the workflow initiator. The same agent should be choosen for both this step and the previous step since the workflow initiator is the same for both and the same rule is being used. The advance with dialog check box is checked in both steps. Both step refer to tasks that are both marked as synchronus object methods and object method with dialog.
For testing purposes, I changed the agent determination in both workflow steps to be the workflow initiator and ran it. The workflow stopped at the approve trip facts step as expected and when I choose reject trip, I was taken immediately to the create mail task that task TS20000139 runs as it should. I tried creating a trip as the employee and the manager and it work properly in both occasions regardless of which user the trip was created under when just workflow initiator is used for agent determination.
I ran SWI2_DIAG to look at the errors that occurred when it stopped in error when I used rule 168. According to the error message, the approve trip fact step completed successfully, but the enter and send message step failed with no agent found. Following is the error message:
Workflow WS90000048 no. 000000277688 activity 0000000476 role 'AC00000168': No agent found
What I don't understand is that the agent determination for the approve trip facts step which works perfectly uses the same agent determination as the enter and send message step which is terminating with an error. Also when I change both steps to use workflow initiator as the agent, then they both work perfectly.
Help, Please

Thanks Martin,
I used your suggestion and passed the actual agent from the prior task to the container and then used this value as an expression to determine the agent for the step that was causing me pain. Now the workflow step is continuing properly and automatically bringing up the create message step as expected.
Arghadip,
I tried your idea about creating a copy of the standard delivered workflow and even set it as a general task and I got the same result as with the standard SAP (error with no agent found).
Thanks again for everyone's assistance
