Multiple Levels in Travel Request Workflow

Hi All,

I want to implement the Travel Workflow for multiple levels. For a single level the agent will be maintained in the Rule. But for multiple levels, i.e, for consecutive 3 or 4 levels, how to determine the agents for next level.

I have searched many posts online but all of them says use a loop for multiple levels, but doesn't mention how to do the agent determination for multiple levels as we have the option to set only one level agent in the Rule.

Please help me with the details steps if anyone has the solution

regards
