My first job out of university was with a large international German electronics manufacturer with a rude sounding name; they'd sponsored me through uni.
I was tasked with generating multiple EDIFACT messages from the SQL database using VB, one of which was the INVOIC file. One of the fields in the message, I can't remember which, indicated by use of a single character whether the message was an invoice or a credit. I got it the wrong way around and accidentally sent out around DM 10 million of credit that should have been invoices.
Fortunately we only invoiced our regional offices around the world, not the end customer, and the mistake was quickly spotted.
