Help: How can I issue a Purchase Order from Plan

In Navision, When I want to make a Purchase Order according the Planing Worksheet, how to do that in Navision? Can you tell me the steps? Thanks lot.

In Purchase & Payables. Try requisition worksheet. Functions Calculate Plan, Accept Action message = Yes, and Functions Carry out action messages. But you need the data setup to be correct on the item or sku card. Good luck.
