HOW TO KNOW THE STATUS OF WORKFLOW

Hi,

I am using a standard workflow for aproval of Appropriation Requests (App. Req.)

We have 5 approvals(persons) in the heiarachy.

I want to know the status of a App. Req.

i.e which persons are approved

at which person it is pending

or whether it is approved by all the 5 persons

In which table I get this information ois there any Function module to get this info?

Plz reply
