decision trees can not be parameterized?

in the resuse and specialization chapter quiz, there is a question


Which of the following statements about parameterization is FALSE? (Choose One)

Decision Tree rules can be parameterized.

It is possible to make a parameter required.

A parameter can be of type string, Boolean, integer, or page name.

Filling in a parameter description is recommended, but not required.

Circumstanced rules can be parameterized.



How can this answer be correct? Decision trees can be parameterized. The rule form allows it in PRPC 7.

Can someone explain?

Dear KURAS1,


Decision Tree can indeed be parameterized. This has been escalated for review. Please ignore this question.

According to the video transcript:


Only certain rule types can be parameterized  They are:

  • Sections
  • Flows
  • Data Transforms
  • Activities
  • Functions
  • Messages
  • Collections


My question here is, there are some differences betwen the parameters for desicion tree and the activities; for activities you can say if a parameter would be in or out... is this the main reason?

Dear mariopleitez,


This is not the reason why the question needs a review. But you are right that there is an IN and OUT parameter.  Sometimes after executing the activity, you may want to pass some values to the next step in the flow, so you use an OUT parameter for this.
