Record ACH payment under Manual/Print Quick checks

My company has many ACH payments set up in our banking system so we have to record all those payments in Sage. I am the new to the company so I am not aware of the steps of how to record it.

I have a couple of questions below.

1. Should I enter any commitment in JC before I enter manual check IN AP? I try to enter one manual payment in AP, after I enter the check and invoice info the next window wants me to choose the commitment so I am a little bit confuse here.

2. For the vendor invoice yes I know we have to enter the commitment first so when we enter the invoice we can pick which commitment we need but since these ACH are all like monthly utility payments should I do the same thing as regular invoices?

3. If I have to enter commitment for these ACH payments same as regular invoices where I can find the info which the commitment we entered previously for these ACH (Utilities)

4. When I run the commitment cost by vendor I do see we have spent some but it only shows the total. Is there anywhere I can see the breakdown? For example, we paid $570 in February and $400 in January but under commitment cost says we paid $2,000 in total so I am need to know if $2,000 we paid in total in included the monthly payment or some specific item.

Thank you.
