Internal Requisition not getting approved

 I create an Internal requisition and then click on Approve > In the approve document form, the submit for approval is checked> Click on OK. When I requery the requisition the status is still 'Incomplete'

The Job linked to the employee id which I'm using has the 'Approve Internal Requisition' and a approval group associated. The approval group also has a high amount limit and all accounts defined in the account range.

I checked the following tables

Select * from apps.PO_REQUISITION_HEADERS_ALL

Select * from apps.PO_REQUISITION_LINES_ALL

Select * from apps.po_wf_debug where itemtype = 'REQAPPRV'

and there are no records showing in the 3rd query. The first 2 queries return the requsitions that I have created. I also ran the workflow background process with Item type PO Requsition approval and the IR is still in incomplete status. Could you let me know if there is any setup step that I'm missing ?
