That code as you post it will fire on ANY field change...

Hi, is it possible to isolate the fieldChanged event/function to occur/trigger only when one specific field is changed (i.e. item)? If I just change the item on the sublist without any other code firing in my function, the event triggers/fires 2 additional times (rate, description), causing an addional item to be added.

try using the post sourcing entry point instead

Genius! Thank you! I was racking my brains on this for hours. I actually tried post sourcing before posting in slack, but I erroneously left the field changed entry active.

committing before sourcing is complete usually causes problems, though its pretty rare to try to commit the line in a fieldChange or postSourcing in general

Done. Perfecto!
