Hello,
I need help, I need to create an invoice system and the conditions are:
List "invoices"
field dropdown "ivoices__prefix1"
result: prefix1+autoincrement
IVOICE NUM: 2017-0001, 2017-0002, 2017-0003, ...
and when I change the dropdown:
INVOICE NUM: 2018-0001, 2018-0002, 2018-0003, ...
Please help, I've been looking for any information usefull or that I could understand, but nothing.
It is very urgent because I have to get ready this before 2018.
Thanks,
