Intializing Planning Area

Hello Gurus,

I understand that when we initialize a planning area then we create liveCache memory for the planning area. Now we can also intialize individual key figure with different time horizon.

However, I want to know what happens when we reinitialize the time series for a planning area which is already in use? Does it deletes all the key figure values or something else happens?

Kindly help me understand the concept.

Thanks,

Sanju
