How the sequence of Automatic Contract Numbering decided
I have done the required configuration to enable automatic numbering of 'InterProject Type Contracts'. Contract numbers are now getting generated automatically however I am not sure how the numbering sequence is being decided. The first contract number that I generated was 1 and then the next contract number was 1001 then 1002 then 1003 and after that numbering jumped to 2001. I want to understand on what basis the numbering is being decided.
Please see the attached document for the configuration and contract numbering screenshot.
