Sell Items Assembled to Order

If the Assembly Policy field on the item card of an assembly item is Assemble-to-Order, then the item is not expected to be in inventory, and it must be assembled specifically to a sales order. When you enter the item on a sales order line, then an assembly order is automatically created and linked to the sales order.


If some assemble-to-order items are already in inventory, then you can deduct that quantity from the assembly order and reserve it from inventory. For more information, see Sell Inventory Items in Assemble-to-Order Flows.

In this procedure, you process the sale of an item that will be assembled according to specifications that are requested by the customer. The steps include initiating the sales order line, customizing the assembly item by editing its components and resources, checking availability to establish a delivery date, and releasing the sales order to be assembled and immediately shipped.


The following procedure does not include the standard sales order steps before the step where you enter the assemble-to-order item on a sales order line.

To sell an item that is assembled to order

  1. Choose the Lightbulb that opens the Tell Me feature. icon, enter Sales Orders, and then choose the related link.

  2. Create a sales order. For more information, see Sell Products.

  3. In the No. field, enter an item that is set up to be assembled to order.

  4. In the Location Code field, define which location the item will be sold from. The assembly process will occur at that location.

  5. In the Quantity field, enter how many units to sell.


    If one or more components of the requested assembly item quantity are not available, then a detailed availability warning page opens. For more information, see Assembly Availability.

    An assembly order is now automatically created and linked to the sales order line. The due date of this assembly order is synchronized with the shipment date of the sales order line.

    The quantity to sell is copied to the Qty. to Assemble to Order field, which indicates that the item setup expects the full quantity on the sales line to be assembled to the order. You can decrease the quantity to assemble to order, such as if you know that some items are already available. For more information, see Sell Inventory Items in Assemble-to-Order Flows.

  6. To reflect that the customer wants an additional item in a kit, on the Lines FastTab, choose the Line action, choose the Assemble to Order action, and then choose the Assemble-to-Order Lines action to view and change the standard assembly components. Alternatively, choose the Qty. to Assemble to Order field.

  7. On the Assemble-to-Order Lines page, create a new line of type Item for the requested additional kit content. The line represents an additional assembly component.

    You could also customize the order by increasing the quantity of one standard item in the kit. You can do this by increasing the value in the Quantity Per field on the specific assembly order line.


    The Assemble-to-Order Lines page only contains the basic fields that a salesperson is expected to use to customize the component list, add item tracking numbers, or to solve component availability issues. To see more assembly order information, such as the assembly order starting date, choose the Show Documents action. This opens a full view of the assembly order that is linked to the sales order line. You cannot change the contents of most fields on the assembly order header, and you cannot post assembly output from it because you must use shipment posting of the sales order line.

    On the header of linked assembly orders, only the Starting Date field can be changed to enable assembly workers to specify a date that is earlier than the due date when they will start the process. All fields on the lines of the linked assembly order can be changed so that warehouse workers can enter consumption figures during the process.

  8. Review or react to component availability issues. For example, select an available substitute item.

  9. Close the Assemble-to-Order Lines page. The linked assembly order is now ready to start to assemble the customized items by the due date.

  10. On the sales order, choose the Release action to notify the assembly department that the assembly process can start.

  11. In the assembly department, perform the steps of assembling the items that are sold in this procedure. For more information, see Assemble Items.


Be aware that item substitutions will not automatically cause an item to be replaced by another item, for example when creating a sales order or in a BOM. Instead, you will be alerted to the fact that a substitution is available to you.
