With Forms 10.3.1, the ability to transfer Forms XML process files and the associated lookup rules was introduced whereby the rules would be disabled on upload to different Forms server. I have used this successfully and have also encountered where it is not working getting LFF4107 message.
Instead of the Imported Rules being turned off, they aren't present at all.
For this particular process, it was successfully transferred in one direction but not in the reverse direction. Both servers on Forms 10.3.1. Anyone else experience this?
