Approval Hierarhcy (Departmental approval)

Summary:

Hi we are creating approval hierarchy using jobs.

I need to maintain different hierachies based on the department. (How to do this)

For ex : HR, hierarhcy as follows.

Job Level

1. Senior manager HR 10

2. DGM HR 20

Engineering hierarchy as follows.

Job Level

1. Senior manager Engineering 10

2. DGM Engineering 20

Levels are 10 for senior level, and 20 for DGM Level.

Based on the expense type, if i want to route it to HR or engineering, how to do that

as in levels are the same. So how can the system identify if my starting participant is senior manager HR, and next participant should be dgm hr and NOT DGM Engineering.
