What function deals with barcodes?

I am look ing for a function that makes the communication between the barcode reader and the EnterpriseOne. I need to change it. Can anyone help me please, its really important!!!

I don't quite get the question, what do you mean by function? Generally, from my knowledge, the interface to Edwards is via API call in turn running JDE BSFN's

I agree that this question is a little vague. The questioner may care to visit the web site of a company called Scylark Ltd here in the UK. There is some great information there for you (www.scylark.com). Drop them a line, maybe they can tell you more.

Here is another site which may lend some help.
