In our Application, Process models are chained. User can step back to any node anytime. So there are few nodes e.g. save data to DB , should be called only once. Even if user steps back many times, node should be executed once. Please help m to know, how to configure node to run only once?
Should we go for MNI with instance number=1 only?

Are you only executing the save to database node once to prevent duplicate rows? If so, have you considered using the output on the save node to place the saved values into the pv? That way each time it will just update the saved values.
