Need your help with auto-increment
I have a small question. I need to make my purchase order number to be like XXX-YY, where XXX is 3-digit auto-increment serial number and YY is last 2 digits of current year (ex. 10) and I want this counter to reset each year.
I found a lot of stuff around like that, but I can't really put it all together. I'm sorry for taking your time, but please try to help. Thank you so much!
