Tip of the Week: Preallocations in Sicon Manufacturing

Preallocating Items With Sicon Manufacturing

Sicon Manufacturing Preallocations are a great way to preset where an item will be used or where it will come from in advance of any stock movement.

Preallocations can relate to Works Orders, Sales Orders, Purchase Orders and Stock Transfers.

This is a great way to reserve stock before you make or receive any items and ensure stock is located correctly upon receipt of goods.

In this tip of the week, we’ll show you around Preallocations in Sicon Manufacturing.


When you create a Works Order which contains a subassembly item, the subassembly window will pop up. To create a sub assembly works order, tick Create sub assembly, complete any details as appropriate and click Ok.

This creates a subassembly Works Order which will be preallocated to the parent Works Order.

To see the preallocations within a works order, click the Preallocations tab.

Within a subassembly works order, on the Preallocations tab, you can see that this finished item is linked to WO00000287.

To manually add preallocations to component lines, click New.

To amend a preallocation click Amend.

In this example, we’ll click New to preallocate the components required to a live purchase order.

A create preallocations window pops up, where we select the document number and enter the quantity.

Please note: we do have the ability to preallocate a greater quantity than what’s in stock if needed.

If a works order is generated from a sales order, the finished item will be preallocated to the sales order before the item has been built.

To create purchase orders from within the works order, click Create POs.

Select the relevant purchase orders and click Create Selected Purchase Orders.

This creates a preallocation between the purchase order and the works order.

Please note: After you’ve made an update, switch to a different tab and go back to the tab you were working on to see updates.

The preallocation is visible when you receive goods against a purchase order.

To see this in action, click Confirm Goods Received and refer to the WO Preallocations column. Click the blue text to see which works orders require the stock and when production will start.

This is useful if you want to send the stock directly to the manufacturing location instead of storing it.

On the Receive Preallocations screen, you can see how much stock has been preallocated, which you can adjust if needed using the Edit button.

Click Save to continue.

When the receipt is complete, the works order will be updated to show the received stock as allocated.

Also, the Preallocations tab will show a status of Completed.
