okie dokie, Accounting apparently didn't give enough detail, so here's more info after I did the work:
 
Running AP-I Print Aging
From Date 05/06/09
Type of Report to print = A/P Listing
Vendor range is specified
Print Source Currency
Text Mode = N
Include Detail, Open and Paid Items
A/P Listing Start Date 01/01/09
A/P Listing for Terms Type = All types
Sort not chosen (running for one vendor)
Invoice Description IS CHECKED
No Follow up Notes
 
Whether we use t6API1, t6API2, T6API2A, T6API3, none show the check # for a payment. Here's what we see:
 
Vendor  Telephone   InvDate Number Descr Invoices Pmts/Credits
Vendor XX   xxx-xxx-xxxx    01/13/09    4098  P/O#:  8353  2438.00    0.00
Vendor XX   xxx-xxx-xxxx    01/15/09               Payment      0.00      -565.80
Vendor XX   xxx-xxx-xxxx     02/06/09              Payment      0.00     -2421.04
Venodr XX   xxx-xxx-xxxx     03/18/09    4711   P/O#: 8512   406.25   0.00
Vendor XX   xxx-xxx-xxxx      04/23/09              Payment      0.00      -406.25
 
So it shows the invoice numbers, but does not show the check #s for the payments.  This is consistent with any vendor.  It used to show both.
 
Text mode shows the correct check # for payments but not the correct invoice number, it shows something different.  
 
Date of the RTMS:
t6api1.rtm = 11/05/2008
t6api2.rtm = 02/03/2009
t6api2.rtm = 11/05/2008
t6api3.rtm =  11/05/2008
 
AP-I Print Aging is ISTS Enhancement 11/04/08
 
What else do you need to know?

As I mentioned in my GL-E post, AP-C items show up correctly, but AP-F and AP-H items (payments) do not--they do not show anything, and they should be showing the check# when we print a vendor transaction listing.

Darlene,
 
Thanks - I'll send you a PM.  No way I'd ever post my email address on a public forum!!!!!
