Ensuring that a card or page variable is saved
From DataMiner 10.2.0/10.1.2 onwards, it is possible to have a card or page variable saved across sessions.
To do so, place the following prefix before the variable name:
__saved_
The variable is then saved in a separate .dat file located in the following folder on the client machine: C:\Users\{Username}\AppData\Roaming\Skyline\DataMiner. When a variable is saved, if a user reopens a card with that variable, the variable will be set to the last saved value.
