Hi Anjana,
Regarding the separation of VAN and AS2 for 997-
How many vendors you have in total. what is the condition parameter. is it based on Vendor number - ISA or GS ids?
There are 2 options.
If the number of vendors is less, you can create different EDISeparator sender channels looking for specific vendor numbers for AS2 and VAN, route it appropriately.
or
Have one EDI Sender channel for 997 taking all acks.
just use the ISA or GS id in receiver or interface routing to route to appropriate receiver.
if there are multiple ids you can use or option in your condition editor.
When you want to restrict the length to 80. Which field in the 997.
