Content (please ensure you mask any confidential information):

Can you add expense items(non-inventory items) as a material on a work definition?

We'd like to include on work definition for information purposes, but don't want to issue or backflush.

I know we can use supply type Bulk, but can I use this if item is a non-inventory item?

I can't find anything in the documentation about non-inventory items on work definitions.
