Document naming confusion

I have set naming series for my custom doctype as

“REP.##.DD.MM.YY.”

when i set naming series i think ## (2 digit) going upto 99 and then again start from 01, but it’s not working like that it going upto 788 (3 digit) and more

any setting for this ?

Hi @nilpatel42

thank you for reply @Mohammadali

i carefully read the post,
but i think my question is not included in that post

“##” meaning is upto maximum 2 digit or not ?
