Topic: Dimension of every order item

Hi experts,

I'm new to FA and I have a question:
Is it possible to assign dimension manually to every purchase/sales order/invoice item? We need project basis reports for our NPO. I found a topic suggesting changing the PHP source, but i don't see what to change there:

Re: Dimension of every order item

You can put dimensions on Customers, Suppliers, Sales Deliveries and Sales Invoices.
