Hi Michael If you take a look at my previous thread here from a week or so back you'll see the problem you run into when trying to apply that to the transactions I posted in this thread.
https://groups.google.com/forum/#!topic/ledger-cli/bqu-qNr6cjM Consider: 2017-10-01 * Opening Balance Assets:CurrentAccount $1000 Equity:OpeningBalance 2017-10-02 * Savings Assets:CurrentAccount:Savings $100 Assets:CurrentAccount 2017-10-03 * Assertion [Assets:CurrentAccount] $0 = $1000 That final balance assertion fails for the same reason I mentioned in my second post in the earlier thread: that assertion refers not to the summed-up total of everything in *or under* Assets:CurrentAccount (as you'd see in the output of ledger b Assets:CurrentAccount), but the amount that lives in that *exact* location (which you might write in a balance command as '^Assets:CurrentAccount$'). So $1000 errors, and $900 does not. That means I can't record the total balance of that real account, which is what I'm after. That's what motivated my use of assertion value expressions, with which I guess I've either run into a bug, or I don't understand something (see my previous post in this thread). I get the impression that transferring between subaccounts in this way suggested here earlier, is a bit of a dark corner of ledger that's not terribly well supported? I'm keen to hear about other approaches, but so far I'm running into roadblocks whichever way I try to tackle using ledger the problem I set out in that first thread (which is the same basic problem I'm trying to solve here in this thread, though my question here was about a detail). I guess I should either dust off my very dusty C++ and try to fix it, or try one of the ledger spinoffs like beancount... maybe there are beancount / hledger people here who can comment re whether those systems have ways to tackle the problem from the thread linked above?
