Hi Willie,

You can create a wizard form based on osv.osv_memory class and its associated view, to see this you can check the view 'view_purchase_requisition_partner' and the class 'purchase.requisition.partner' in the purchase_requisition module. This view appears when a user clicks the 'Create Purchase Order' from a purchase requisition screen
