# Allow kitting of WIP inventory for outside processing

> Let inventory that is out at a supplier on an outside-processing purchase order be kitted while it is still in WIP.

Inventory in **WIP** is not kittable. When this setting is on, one exception applies: inventory linked to a purchase order line through an [outside-processing](/build-hardware/runs-and-execution/outside-processing) run step can be kitted while it is still in **WIP**. All other WIP inventory stays un-kittable.

The exception applies everywhere a kit draws on inventory: the kitting picker, the kit's inventory viewer, and barcode scanning.

## Allow kitting of WIP inventory for OSP

1. In ION, go to **Settings > Supply Chain > Parts Inventory**.
2. Turn on **Allow kitting of WIP inventory for OSP**.
