New Condition Type

Dear SD guruu2019s

I have created a sales order which is in past date and i have created a New condition type which is in present date.

So i need to change the pricing date .My query is that whether i should got to VK11 to over write the pricing date or i should use the VK12 and change the pricing .As per my understanding we always use VK11 to overwrite the new date.

Plz help.
