In the customizing below, you could see there are totally three kinds of variable: Simple, structure and table.
For BRF+ project, the rule is very simple, we need only to take care all the simple variables, as only simple variable could be used for user input and then participate in the rule definition. The left two kinds, structure and table are just used for container purpose.
In the element visual layout design, you could observe that only simple variables within a structure variable or a table variable could be dragged from the variable tree and drop on the left UI part.
The simple variable acts as the leaf node in the variable hierarchy tree.
Figure1: only simple variables within structure variables could be used in element layout
Figure2: only simple variables within table variables could be used in element layout
