EDI Webpad allows you to generate acknowledgments for X12 and EDIFACT. You need to have an EDI file translated into JSON to use this functionality.
To generate an acknowledgment, hit the 997 or 999 buttons for X12, and CONTRL for EDIFACT. All generated acknowledgments will be batched under the same interchange.
The generator uses the original interchange and group (if any) headers as headers for the generated acknowledgment, with the sender and receiver id and qualifier swapped, and the interchange reference number set to 1. You can amend the reference number manually if you need to.
All generated groups and transactions also have their respective reference numbers set to start from 1.
Technical acknowledgments are not generated at all. You'll need to utilize the API for TA1s or technical CONTRLs.
