You’re right. Missed it while scrolling. Regarding the parent discussion, a classic statement is also two-sided. So, you need to collect sources (debit) and destinations (credit).

It is definitely possible to make each side of transaction a different record, but you have to link them, so there would be another ID for a transaction to group later. It is always there in any case, but you are either joining while getting a balance or grouping while reconstructing transactions for reports. So, it depends on the primary load: lots of transactions to register or lots of reports to provide. Both are used.
