I have field name AWBNumber, I need that field to be autonumber each time data is entered in that table, the AWBNumber needs to be a 11-digit number, custom sequence, and doesn't repeat itself.
the sequence should be like this:
61000100000 +1
61000100001 +1
61000100002 +1
61000100003 +1
61000100004 +6
61000100010 +1
61000100011 +1
and so on...

Is there any solution for this? Should I use the autonumber data type?
Thanks.

Access does not support autonumber with defined starting number, so i guess you will have to programmatically control it

AutoNumber is a Long behind the scenes, so it will not support an 11 digit number (Long maxes out at ~2.1 billion).ashish908,The Access UI does not support it, but there are ways to do it nonetheless:http://www.experts-exchange.com/Microsoft/Development/MS_Access/Q_20676131.htmlPatrick

CurrentDb.Execute "ALTER TABLE MyTable ALTER Column CustID Counter (100,5)"
Starts from 100 and increases by 5

in that case above, what would be the data type?

>>in that case above, what would be the data type?AutoNumber, but stored as LongAs I already indicated, if you need an 11-digit number, AutoNumber is not an option for you.
