Multi period Accounting -- How to capture deferral information in PO and get them to AP Invoice

Hi P2P Gurus,

Scenario: Implement MPA approach to prorate Insurance and Rent type of expenses which are paid at the beginning of the period and expense should be recognized over a period.

A Purchase order will be issued for these expenses -- Like to capture Deferral information like "Expense Type" , Deferral start date and Deferral End date in Purchase order.

After PO is matching in AP -- we would like to get this information populated in Invoice line

a) Deferral flag

b) Deferral Expense type

c) Deferral Start Date

d) Deferral End Date

Looking for options on how to capture additional fields in Purchase order and get these data into AP with no manual input.
