Last Invoice Number

SOLVED

An invoice 1000001 was created when our company was currently on invoice 341912.  As per Sage, the next invoice is automatically 1000001.

I would like to know how we can go about changing the "last invoice number" so that we can get back to our previous invoice numbering without having to keep a hard copy list to update whenever an invoice is created.

Thanks in advance for any help anyone can give.
