When entering Stock on a Sales Order detail line, if the Works Order Processing module has been unlocked and the Stock item you have selected is an Assembly type item with a Bill of Materials, additional fields will be available to enable you to create a Works Order to manufacture the stock or, to associate the transaction with an existing Works Order.

When an Assembly type Stock item is selected for a Sales Order Detail line, a drop-down menu of Works Order options will be displayed on the Detail window.

The list has three options: WO; BTB and Stock.

WO (Works Order), a button will be activated to enable you to 'Associate the Order with an existing Works Order' or 'Create a new Works Order'.

BTB (Back to Back) the item will be added to the Consolidated Requests to enable you to raise a Purchase Order.

Stock select this additional option if you expect to take the item from stock. The item will not be added to the Consolidated Requests for purchasing but you will still be able to associate the order line with a Works Order at a later time if you wish.

The default value of this menu will depend on the settings on the Stock record.

If the Default BoM action for the Assembly has been set to Manufacture: the menu will default to WO (Works Order).

If the Default BoM action for the Assembly has been set to Purchase/BTB: the menu will default to BTB (Back to Back).

The menu option can be changed and the Stock option selected if required.

The Default BoM action for the Assembly is set on the Parts window opened from the Assembly icon on the Stock record.
