For navigating responsibilities, unfortunately you cannot simply select the one you want with a single action.
You could do one of two things:
1) Individually click on each component of the tree to expand/navigate your way to the area of the responsibility you want, one at a time. A collapsed category will hide its children from the HTML code and as a result: the business object won't find it.
2) Set preferences, for the EBS user assigned to your process, to have EBS automatically navigate to a specific responsibility/section upon logging into EBS.
