Searal number, that is my primary key and ID #
I set up my system to have a serial number for each new invoice. I'm importing old invoices in.
I need to shut off the serial number and hand enter a few invoices. Ive tried changing it to just a number, and Ive changed it to a text but
I still get the error message that this field is not modifiable.
Its not a calculation filed...
How do i change it?
