Hello baskar.g,

You need to know if you're always connected or not.

If you are always connected to the SharePoint server then you can maintain
a list of PO numbers issued. You could then use that list to ensure you don't
have duplicates when you issue a new PO. Be very careful to ensure that your
system copes with two users simultaneously attempting to get a new PO. It
is possible that you end up with duplicates if you don't consider this possibility.

If you are disconnected sometimes, then it would be useful to assign a GUID
as the PO number (or at least a hidden PO number). Then use something like
the date time entered as the PO. Something like 20041128164321, but salt
it with a hash of the user entering the PO. This should ensure unique IDs.

Does that help?

James.
