We set the eVar2 as most recent and expire after visit as we need to persist this eVar in our application.

However in the flow for one scenario, we need to clear this eVar and set to not triggered and also need to clear the persisted value

Scenaio -

Consider a booking flow and we provide an offer for  few customers

when they start the booking flow we apply this offer and tracking using an eVar 2.

eVar 2 = offer 1  and the final bookings are under this offer 1

If they are two offers if the user select the second offer we are overwriting eVar2 = offer 2

And corresponding bookings are attributed to that offer 2

Also in the booking flow customer can remove this offer in this time we don't need to track this booking under any offer.

In this case how to remove the previous eVar 2 value as in this case our system is not passing any offer code.

What is the best practice in this case? Is that okay if we pass eVar2 = " " to over write the previous persisted value.
