In odoo14 the payments behavior has changed and worked with for different accounts for one bank account (bank account, suspend account, outstanding payment account, outstanding receipt account) in the journal of this bank. In some cases, we overjumped the outstanding accounts because it is a mess with a lot of accounts for one bank. The behavior was explained and discussed in this post: https://www.odoo.com/de_DE/forum/hilfe-1/v14-change-in-payment-behavior-how-do-the-suspense-and-outstanding-payment-accounts-change-the-journal-entries-posted-177592

Now we are thinking about to migrate to Odoo15 and I saw that there the behavior of the Bank journal has changed again: Only one Journal for all bank accounts with payment methods, and no extra outstanding accounts although the payment behavior looks like the same with outstanding payments. Can somebody explain this new behavior and what is with the existing outstanding payment accounts?
