lift off check

Sirs,

In operation condition some supports are lifting up means DY is greater than zero but sustained condition those supports are taking load.
BUt in both case oper. & sustain case those stress are within allowable.

In this condition somebody advised to go lift of check.
How to do lift off check?
I think we have to remove the lifted (DY>0) supports and run the model and check the stress in Operating condition only not sustain case ?

Is it correct or not? Pl clarify.
