Requisitions or Purchase Orders can be added to Inventory, Standard, Labor or Subcontractor Service detail lines in a Job or Sales Order. This provides the flexibility to order anything from an existing inventory item (stock or non stock), to a miscellaneous service or part, as well as a subcontractor service. The number of Requisitions or Purchase Orders that can be added to a Job or Sale Order is unlimited. New nodes appear in the tree of the Document under the detail line selected (Item or Service), when a Requisition or Purchase Order is created.  Note with the introduction of Serialized Inventory and Lot Tracking within Sage Accpac 5.6 nothing has changed you still need to purchase Service Manager Purchase Order Add-on Module and you still need to purchase Sage Accpac PO activation within 5.6.
