R12 Does the KITs are neither Transactable nor Stockable items

Hello

I have just setup some Kits according the following note

What are the Item attribute settings required to create a PTO (Kit) Item? (Doc ID 1093134.1)

In my view the KIT's must be neither Transactable nor Stockable ítems , however when I was doing a Shipping I got an error message that the KIT was not Transactable.

Please Advise

Pick–to–Order (PTO) Model
An item with an associated bill of material with optional and included items.

At order entry, the configurator is used to choose the optional items to include for the order.

The order picker gets a detailed list of the chosen options and included items to gather as separately finished items just before the order is shipped.
