How to call a DT that is in data layer in a DT that is in work layer

How to call a DT that is in data layer in a DT that is in work layer-Will Apply Data Transform method work if we straightaway give the name of the data class DT and try to call it in work class DT?

Technically it is possible to call a DT from a work layer calling a data layer DT rule shown in the attachment. I tried doing so it gets called and will work. But more easy way is to define the class name to be called with a name and its class in the Pages and Classes tab of the calling DT and use the defined name to call members of its class with a dot. Ex: AdminPage.pyNewAppDefaults with Apply DataTransform.

so if i don’t define the class name under pages and classes and directly use it will it work?

Yes. It will work.
