Hello,
For me, the most wanted feature and the only thing that is blocking the full implementation of erpnext in my company is the hability to deal with multiple due dates on purchase and sales, as described here [Feature Request] Multiple due dates in the same invoice · Issue #6301 · frappe/erpnext · GitHub apparently is something that will please a lot of people
Other than that, production order should have a quicker way to start and finish, the current cycle takes a lot of time and is almost impossible to deal with 1000 orders/day (my case), this was discussed on Manufacturing process
Multiple actions should be awesome too, for example approve, close, workflow transitions, start or finish production orders and so on.
Decimal separator according to language option, the decimal separator works fine using the erpnext, but importing can be a mess, the values are considered without the separator, it confuses some users and can cause problems if not checked after import.
CSV separator according to language setup too, it can be painfull, mainly to final users, because it is necessary to import as a text file and go trough a menu on excel or libreoffice to choose codification, separator, etc. If I configure the default separator as “,” and not “;” I have to go trough the same menu to open local files, this was suggested here [enhancement] option to choose separator on csv files · Issue #8520 · frappe/erpnext · GitHub
Thanks
