If you have MANager privileges (type MAN at the system prompt), you can run

REPORTS 
RSTATUS         Status report of Requisitions in process

to have a full list of pending reqs emailed to you.

Once you know the req #, you can (again, on the MAN menu), look up an individual req, under

MISC
REQ1            View requisition status by req number 

Perhaps you want to know who has yet to approve (where are they stuck?)…  run the RSTATUS report and that should answer this question.
