Create an input option
The same input options are available for Open Order Templates as for templates for users, groups, and contacts. You can also use the same creation rules and constraints (except for the uniqueness constraint, which can only be used in templates for new users with AD attributes).
There are additional possibilities for inputs, descriptions, visibility control and validity checks, which can only be used in Open Order templates in the Web client (not in the Rich Client).
An overview of available input options can be found here.
