No. series increment

Dear Folks,

Hope you all are doing great.

I am facing a very big issue with the No.series in the journals no. are not incrementing automatically. I have set up the No. series setup properly with starting and last No. used I am not mentioning any posting No. series as the users want to capture the same No. after posting too.

Kindly Suggest a solution for this issue.

Many thanks in advance.
