Re: Cleo 3780 & Sterling
This is the reason that a VAN is used. All of the
VAN's that I have worked with will put data in my
mailbox either wrapped or unwrapped. This is part of
the VALUE added. I just have to setup one type of
receive processing.
When setting up direct connections then each
connection has to be maintained based on how the
trading partner creates the data.
Cheers,
