Hey, I am trying to change the SalesOrder from Pendin gApproval to Pending Fulfillment. It seems like it works, however when I refresh the Sales Order it still says "Pending approval". Anyone have any ideas why or how to update the status of a sales order?

set the orderstatus field to 'B'

did that. It keeps reverting back to A

probably some workflow or something else doing it?

I've disabled everything and it still seems to revert it for some reason.

do you have any Advanced Approval turned on? eg under setup->Accounting->Accoutning Settings->Approval Routing?
