What are constants?

Constants are data sources with a fixed value. Their value is not calculated while a process is running, but is defined by the user when creating a data flow.

If a constant does not have a value, the name is used as the value. A constant always has a certain data type, such as string or Boolean.

Constants with readable values are displayed in the data flow with their name and their values. For constants that are only machine-readable, only the name is displayed, for example, password constants.

The following data types are available for constants:

  • String

  • Boolean

  • Decimal

  • Date

  • Duration

  • Language

  • Password

  • Document metadata

  • Folder

  • Localized string

Constants can have different values in different languages.
