Problem In Creating Serial Nos

Hi All,

I am an abaper.I have one issue in CO01 transaction.There is a requirement in my project that Serial No generation has to take month of start date in consideration.I searched for any user exit pasiing start date but none of the had it.Now i can do it only if the Basic Start date is saved in DB table at the time of Releasing PO's.

Can any of the gurus tell me if it is so that is "IS the start date saved in the DB table when we release the PO".

On what all criterion can i hit that table to get the date.

Thanks in Advance,

Saket.
