approval workflow for leave request

Hi,

We are using Ess in erp 2004 and EP 7.0, we have to configure the current n step workflow in leave request to 1 step, but when I see the ess application in EP, i dont know which workflow it is calling so, i cant make the changes to that workflow.

I'm a new bee to ESS please advice how do I identify which workflow it is triggering.

Thanks,

Swetha
