Duplicity?

[Roger S. <rs...@ma...>]

Hi, I was entering a Vendor invoice, and just to test it I entered another invoice with the same Invoice number and under the same vendor and it allowed me to do that. Am I doing something wrong? or does it allow duplicate invoice numbers under the same vendor?

Invoices are distinguished by an internal ID, not the invoice number or 
a combination of invoice number and name.

So, yes, you can enter the same information again, however, the invoices
are different.

Roger...

If you are concerned that the possibility of creating two invoices 
with the same number is an integrity issue (or a potential for 
confusion), consider trying a UNIQUE constraint on the invoice number 
field.

However, I tried something similar to prevent duplicate customer 
records, and got an error.  If I understand Dieter's explanation, 
this is because the record is created with a null in the id field.  
So, my sggestion may not work for other tables, either.
