I am having a host of users with complaints about the changes in entry screens-  (sort of like going from office 2003 to 2007-- which most love now) But there are several things I agree could be much better:
 
1)In the look-up screen for PO-A the list is from oldest to newest with the cursor on the oldest, unlike the t6 version where the cursor is on the newest, which is much handier.
 
2) The totals for a line item and for the grand total do not show until you have saved the PO AND printed the PO, there is no ability to show lines with totals like in the T6 version.  It's sort of a pain to print preview the PO, discover a mistake, close the print preview and say no, the PO did not print correctly, then wind up with a non-responsive entry screen (I can look up a PO but when I highlight the one I want and hit <enter> I get a PO with 0 in the PO number and the <enter> button takes me nowhere), exit the program and start over.
 
3) I was totally unsuccessful in editing a line in the Evo screen version.  I had to go to the Classic view to access any line on an existing PO.
 
 
Is it possible I have an older version of PO-A?  It is hardly usable the way it is.
 
I have had the most issues with the PO screen so far-- the other screens are mostly the look and the users can fix some of what they object to with the user settings.

I have to agree with Cathyh on T7POA-  It also does not seem to use the PO defaults, as entered in DEF-C.  You can't enter a 2-digit term unless you use F2 to list and select.  Sometimes, if you enter one PO and try to enter a second one, it will burp and you get a 0 PO.  It makes our purchaser scream.
While we're at it, when you go to print the PO, it always asks if you want to make the .RTM you are using the default, no matter how many times you've answered yes in the past.
I have also noticed that there are some T7 versions of other PO programs, although updating via the ADMIN menu does not bring them in.  I tried the one for entering receivers, but it does not create the receiver record in the database.  Are these just betas?
