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.

Are you using standard post codeunits or done any customizations?
did you setup Increment-by No field also in No. Series lines?

sorry for the late reply some changes have been made by the previous team,but while looking in to the code it is same as standard only.
