I'm creating a billing invoice and using the Auto Number feature. It is
possible to change the starting number (eg. from 1 to 0001)?
You should not be using an AutoNumber field for anything other than
assuring that each record's ID is unique.
If you wish to assign an Invoice number in a consecutive fashion,
create your own InvoiceNum field.
You can make it Number datatype, Integer field size.
Then increment it on your form in the InvoiceNum control's Default
Value property:
Nz(DMax("[InvoiceNum]","TableName"),0) + 1
Set the Format property of the field to:
0000
and it will display as 0001, 0002, etc.
