Accounting rules are not defaulting when entering transactions with rules

Hi,

I have setup Items with Accounting Rules and Invoicing Rules (Advance Invoice) on the Invoicing Tab.

When creating an AR transaction with accounting rules, I select the following:

Invoicing Rule  -  'In Advance'

Select 'Line Items'

Select the relevant Item on the 'Main' Tab

However, when I select the 'Rules' Tab, the accounting rule assigned to the Item is not populating the 'Accounting' field.

This is the same for importing invoices via AutoInvoice.

Any thoughts?

Thanks

Jon
