There are fields on the requisition worksheet that are not on the planning worksheet and vice versa which causes confusion especially from a purchasing standpoint related to prices, costs and amounts. If you create a purchase order from the Planning Worksheet, BC will pull the proper price on the PO line, however, you can not see the price and amount in the planning worksheet but you can see it in the requisition worksheet. Alternately the Requisition worksheet does not show item cost (not price) information you can see in the planning worksheet.

Add the Direct Unit Cost to the planning worksheet (purchase price) (it is on the requisition worksheet)
Add the Amount field to the planning worksheet (direct unit cost * qty) (it is on the requisition worksheet)
Add the Unit Cost field to the requisition worksheet (it is on the planning worksheet)
Add the Cost Amount field to the requisition worksheet (it is on the planning worksheet)
