Journal Entry Extra Field Appearing

Start with Bank Charges and then choose the bank Account when making the Journal Entry.

I have the same issue since upgrading from 2.3 to 2.4.
Unfortunately your solution described does not work for me. No matter whether I put the bank account first or second for a journal entry it will insist on the counterparty entry which defaults some vendor and can't be changed therefore making these entries impossible.

I am currently on version Version 2.4.3 Build 09.12.2017, does the latest 2.4 build fix this?

While I am sure there are good reasons for this feature, it strikes me as a little troublesome that there does not seem any way to either disable it nor prevent the automatic opt-in that seems to have resulted from the upgrade.
If this requires a tweak to a config file I am comfortable to do this... that said the documentation of this feature in the Wiki is virtually non existent which doesn't help either. I would be grateful for pointers on how to fix this.
Thank you.

If the bank account is listed in a supplier as an accounts payable account or in a customer as an accounts receivable account, the counterparty field shows up.   So if you do not want the counterparty field, then find the supplier/customer and change it to go to a different account.  If you want to use a different counterparty, then add that bank account to that supplier/customer.

The Customer Branch / Suppliers page can be set to have default accounts Receivable / Payable account.

Usually the supplier would have the default A/P account or a G/L expense account.  Then to pay a supplier (without use a P/O), you would use bank account payment entry and set the From: to the CC account (which was set up as a bank account).

So there is nothing wrong with putting the vendor purchase on a CC card, if it was set up as a bank account.  But it appears to me that you are trying to use the CC card G/L account directly, and you put that G/L account on the supplier default Payable account.

FA does not have a way to assign a bank (or cc) account to a particular supplier that would pop up when the supplier is selected for payment.   I suppose it would be a nice feature if it would do this, although I personally would not use it because the only suppliers that have my credit card are periodic payments like electricity, subscriptions, etc and I handle that with an auto pay extension.

Using the payables account in the manner you have described is unusual because normally a cc card would be used to pay for a variety of G/L accounts, for example, utilities, insurance, consumables, auto & travel, etc.   When a payment is made, the payables account would be one of these G/L accounts and the bank account would be the cc card.

Well, I am at a loss to say anything further.

I am still guessing you neglected to create a "bank account" for your "credit card" (https://frontaccounting.com/fawiki/index.php?n=Help.BankAccounts).

I am then guessing you are trying to directly use the General Journal to directly enter CC expenses using the CC G/L account rather than using Supplier payment or Bank Payment.

That can work, except if you create any suppliers with that CC card as the accounts payable account, which apparently you have done.   I don't think putting the CC G/L account into the supplier is helping you any, and is causing the GJ counterparty problem using this mode of operation.    If you just want to mark the supplier as being paid by CC for informational purposes, you can do that in the supplier bank account field.

Sorry I haven't been able to help.
