Purchase requisitions workflow problem

Hi All,

Have any people help teach us how can setup purchase requisitions workflow?

I tried creating signing limits of document type Purchase requisitions.

my conditions for workflow are

PR < $1 than >$1000 require approval from a MIS Manager

PR <$1000 than >$10000 approval from MIS Manager and a MIS Senior Manager.

I have create one purchase requisitions total price is $30000, normal PR Work flow need MIS Senior manager approve, but my setup workflow when MIS Manger approve tihs PR this order status=complete, don’t work to MIS Senior manager approve.
