Vendor Processing Tab

SOLVED

Hi,  I'm new to Sage 300 Premium (2017) and the system was set up long before my arrival.  I am trying to simplify/automate some processes by using more of the system.  In the vendors screen, on our 3rd tab (processing) there are various options but the one I am wondering about is the delivery method.  I can choose mail/email/contacts email.  What I am wondering is what the delivery method is, I don't want to assume.  All are currently set to mail options although we do quite a few payments by EFT.  The process to send the EFT notices out is manual at the moment.  If I change that delivery method to email, does that mean it will email a copy of the EFT payment to the vendor?  If yes, what are the steps involved after selecting the email option to process/send out the eft payment remittance by the email option.  Thanks in advance!
