Is it possible to do a full year of journal entries in a single import? We had had some users have a go at it but the result was it all going into one month!

Technically it is possible if you use multi file CSV import, but question is number of transactions? Also what if it goes wrong netsuite

Oh no. Go live is just around the corner and this project has been doing it wrong since the end of last year 😉

I don't suggest doing it that way

If you're only importing one entry per month (like an opening trial balance), I think it's fine to do it this way. If you mess up, it's only 12 entries to delete. You'd just want to make sure all the periods you're posting to are open and that the period and/or date are set correctly as for which entries go to which period. One of those things being off is probably what caused all the entries to go to a single period.

In order to do it in a single import you must define external ids by row
