Requisitions can be made from multiple sales orders at once, from the Sales Order list screen. If any items on a sales order has backordered quantity, then a Backordered status is assigned to the order, which is visible as a column on the grid.
You can select one or more orders from the grid to requisition. To assist in locating orders with backordered quantity, you can create and assign a filter to the grid that only displays orders that have the Backordered status with a True value. When all desired orders are highlighted, click the Requisition button to load all items into the Requisition work screen, with Required Quantities equal to the respective sales order Backordered quantities, ignoring any other quantity values from the inventory item.
From here, you can select just those items you want to requisition, and change quantities, costs or vendors for any item. Save all selections to the Requisitions list where the Required Qty is greater than zero. Or if you have user security rights, Process the items immediately into new Purchase or Production Orders, where each manufactured item becomes a new Production Order, and all other items are added to new Purchase Orders for each identified vendor.
