Purchase Invoice Item Type Defaults

Similar to Sales Invoices, Purchase Invoice Item Types can be mapped to default GL Expense accounts. However, in the case of Purchases, since most of the item lines are inventorized, this may be of limited use except in he case of purchases that are directly expensed

These settings override the Invoice Item Type Global GL Settings.

You cannot modify a Purchase Invoice Item type default afterwards. Remove it and recreate the default, if any changes are required.
