If you get a sample JDF from ePace I would be happy to test it on our sandbox AE12. As far as reporting back, AE12.2 does have a task called Integrate with Database. This would allow you to send back information to a external database. Not sure if you have the ability to write to ePace databases. Normally MIS systems do not like 3rd party systems writing into their database. In the past I have written data to a separate database, then via query from MIS I can combine MIS information with other information in the database.
