For experienced FRS users, these are the 3 screens to use:

228 - Purchase Order Line Item Inquiry - Type in p.o. #.

249 - P.O. Invoice Line Inquiry -  In line field - Type in 001 or 002.

244 - P.O. Invoice Line Item Create/Modify - Type in invoice #.
 

What is the screen on FRS that I should start with?
 

Once I have filled in the information on my starting screen, where should I go to see an up-to-date list of invoices that have been paid against this purchase order?

 
What screen should I go to if I wanted more of an invoice breakdown
Example: to see if freight charges were included in the payment?
