I was told to use it as part of my document reference number on order forms. We use our account number, julian date, initial and then number of the document. For example "AL01682014MA01" so they no it came from account AL0168 on Jan 14, 2012, and it was the first document that I did that day. Whether I agree with it or not that is how I have been told to do 2777 forms. A supply tech can probable explain a lot better than me.
