For databases for which you have Database Manager permissions, you can specify calculation scripts as the default database calculations. Thus, for example, you can assign a frequently used script as the default, rather than loading the script each time you want to run its calculation against the database.
Changes to default calculation settings become effective immediately.
To use calculation scripts as default calculations:
From Enterprise View or a custom view, select the database that is associated with the calculation script that you want to use as the default.
Right-click, and select Set, and then Default calculation.
In the Set Default Calculation dialog box, select Use calculation script.
From the list, select a calculation script.
Click OK.
