Lavanya, you can configure TN to perform duplicate checking via the Pre-processing tab on the Processing Rules Details. wM TN User’s Guide has info on this. If you want to check for duplicate for something other than Doc ID, Sender, Receiver, or Doc Type, you would need a custom service and I’m pretty sure you would still need to be storing the custom document attribute for the successful documents so your duplicate checking service can query on that.
Duplicate EDI control number checking can be performed via TN Trading Partner Agreement.
