How can I restrict creating a PR with line type 'Goods' and destination type 'Expense'

Hi Experts!,

The client needs requesters to only be able to make:

1. Internal requisition transfer orders of goods.
2. Only purchase requisitions of services (Line type = Services and Destination type = Expense).

The system should not allow users to create a purchase requisition for goods with destination type equal to expenses (Line type = Goods and Destination type = Expense).

How could this be configured?
How can I restrict the requester from creating a PR with the line type equal to 'Goods' and the destination type equal to 'Expense'?

Thanks in advance for your help.

What was done (temporarily) was to create approval rules that detect these combinations and automatically reject these purchase requisitions.
