Hello,
It is quite difficult to answer without a better understanding of these tables' structure, but here is what I have done to give you a hint.
Table Formation 1
Status is a single select field
Table Formation 2
Status is a single select field
Formation is a text field taking the information from table "Formation 1"
Automation
Trigger set on Status = "Refused" on table "Formation 1"
Action create record in table "Formation 2":
Status is set to "Pack solo" (make sure that this option has been set on the field Status in table "Formation 2")
Field formation is fed from table "Formation 1":
Regards,
Pascal
