Understanding configuration expressions

Depending on the configuration option where it is used, VBScript is available for configuration expressions to either calculate a value (file name, folder, property value, and so on) or to evaluate to True or False to apply an option (input required, field visibility, field read-only, and so on). You can use VBScript expressions in many places in a vault’s configuration, including:

• Property pages
• Document naming
• Folder naming
• Lookup list tables and database queries
• Custom commands
Workflow definitions
• Reports
• Document types
• Database Import Wizard

Each configuration expression is a single VBScript statement to be evaluated. Configuration expressions are limited in that they:

• Cannot contain more than one line of code, although they can call a predefined function that contains multiple lines of code.
• Cannot use variables.
• Should not execute other actions outside the scope of the current document, change property values, invoke long-running functions, or invoke any user interface functions. Such actions can have unexpected or unpredictable results.

You can use a VBScript expression anywhere you see the Meridian Enterprise Script Editor button in Configurator. Clicking the button opens the Meridian Enterprise Script Editor where you can enter a VBScript expression.
