ESS leave request two-level workflow

Hi All,

We have a requirement for a two-level ESS leave workflow and need to know what would be the approach which can be taken to modify the standard 12300111 workflow.

The status should be as follows

STATUS STATUS STATUS

(SENT) Approves (PENDING) Approves (APPROVED)

First Level approver -

> Second level approver -

>

As we can see, we need to add a new status namely, PENDING to the backend PTREQ tables. Can anyone please provide some kind of leads/info on this.

Thanks and Regards

Reshma
