Configuring a Data Definition on a project or model folder automatically introduces a _data variable in the ITP Models of that folder. The variable _data always has the type of this Data Definition. The model developer must fill the variable _data with appropriate content.
Every WIZARD and TEXTBLOCK statement in the ITP Model will implicitly use the _data variable to present repeating elements and fill FieldSet content.
Note
_data is a reserved name. It is not possible to (re)declare any objects with this name in the model language.
