Chances are that most of your dashboards share some features such as variables, colors, and even some visual cues. To ensure that all the apps in the QlikView environment are consistent, and to save some valuable time, you can create standard text files to use them as opening and closing scripts. These files can collect shared functionality, such as:
vToday
or vCurrentYear
HidePrefix
or NullAsValue
You can easily import these files in all your apps by going to Insert | Include Statement.
