I was completely oblivious to the fact that Ledger is flexible with regards
to thousand separator and decimal point character. But even after I add a
non-ambiguous "predeclaration" like this:
2021/01/01 entry0
assets:cash:savings:bca 0,000,000.00 IDR
assets:cash:dana
2021/01/06 entry1
assets:cash:savings:bca 200,0000 IDR
assets:cash:dana
2021/01/06 entry2
assets:cash:savings:bca 100,000 IDR
assets:cash:dana
2021/01/06 entry3
assets:cash:savings:bca 3,050,000 IDR
assets:cash:dana
I still can't make Ledger detect the error in entry1. It still ends up
complaining about entry3. If entry1 is commented out, Ledger now can parse
the file and correctly use the format specified by entry0:
% ledger -f 2.dat bal
0 assets:cash
-3,150,000.00 IDR dana
3,150,000.00 IDR savings:bca
--------------------
In my own use, I just don’t bother writing the thousand separators; a

With the relatively low monetary value of IDR, it's quite helpful as the
numbers can easily go into hundreds of millions or billions. Without the
thousand grouping I would have made even more errors.
