Normally the problem is due to not inclusion on standard modules as modules out of standard are migrated “when possible” so most of the time they are based on old series.
I agree that modules should be proposed for inclusion. We’ve discussed several time with some argentinan comunity members (see Localizacion ES_AR for example) but we are still facing the same problem. There is also Issue 8434: Argentina chart of account - Tryton issue tracker which misses some more feedback about Argentinian usage to have it clear. It will be great if somebody can continue it.
If you think we can do something to help this localization projects become a standard project please let us know.
