Sage 100 v2018 - trying to add a missing PO# to an AR invoice already printed via:
- AR Inv entry
- inv #
- cust # > added PO#.
No other changes are to be made on inv. Print invoice -. . . I continue to update Sales Journal and daily register states nothing in file. PO did not poplate on invoice. Data not selected (nor do I have a box for already printed invoices) HELP.
