Ive recently updated IP to v1.4.10 from v1.4.4.
2016 is over, I want to enter new year for books and all other stuff for my business.
In my country from 01.01. every new invoice created have to start from number 1; for e.q. last invoice # (number/id) in 2016. was 20/W/1 (/W/1 must be with invoice no. by the law…). and first in 2017. must be 1/W/1
Ive tried to created new invoice group with the same unique id and create new invoice in that group.
IP creates invoice and saves draft (that is ok) but when I try to change anything and click Save it trows me an error : “The Invoice # field must contain a unique value.”
In db I can see that invoice in table, and when I change it thru phpmyadmin its ok, but if I try to change anything and save it i get the same problem again.
Ive tried same thing with v1.4.4. and 1.4.10
Is it a bug or am I doing something wrong?
