would like to check / change address when entering voucher in AP-B

in our case the person that enters the vouchers also issues the checks.  i think it would solve our need for a million one time vendors (donations, etc.) to be set up.  we could use a generic vendor (ie. donations) and then edit the address when entering the voucher.  maybe it's an option such as Y, N, maybe, password, etc.

Yes, again the person entering the voucher in A/P-B also prepares the check.  
 
Because there is no security on entering Vendors in AP-A, many times a correct address gets edited by the wrong party, and the payables person needs to exit AP-B upon noticing the wrong address displayed, and correct it in AP-A.  
 
If editing vendors can be done in AP-B, this would save one step and increase productivity, OR is there a way security can be imposed to restrict access to entering REMIT TO ADDRESS in AP-A???

We run even leaner than Karen with a staff of 10 people.  In our case, the same person sets up the vendors, enters the vouchers, pays the bills, signs the check (1 of 2 signers) and reconciles the bank statement.  I know from experiences when she's gone and I do her work.... it would be nice to fix info when you're in AP-B.
 
Also, on the PO side.... sometimes Vendors are set up with basic info when the purcasing person make the initial contact and submits a PO.... would be nice to edit info when entering the Invoice for payment.
 
Again, I think a password/security option is the way to go.  It's the best of both worlds.

i'd like it controlled by the logon password.

that would work for me.
