Multiple 997 Messages

Hi Guys,

We send back a 997-Return receipt message for all the messages we received from one of our supplier over AS2.

But we send also 997 Messages out for return receipt messages from our Supplier when we sent them a message, means we send out a return receipt message to a return receipt message 997 from the supplier, which makes no Sense!

Could you please share or let me know your thoughts on how to overcome this issue?

Thanks in Advance.
