Thank you Peter! I am aware of this method of introducing blank row. What I want to achieve is when I am using .Tree to display the hierarchy, will I be able to introduce blank rows in-between the hierarchy members which is getting dynamically displayed.
You can't do that with standard filters, no. You could create a custom Member List in a Finance Business Rule as explained here, and place your "A#None" strategically in that list, but it's a bit of work and I'd do it only if you plan to use it in multiple reports. Otherwise, the solution shown by ChristianW is probably the best approximation.
