How to load and process text data on upper-levels of a dimension in icCube?

Question

I want to load textual data on any member in a natural hierarchy in icCube, but I am not able to display the textual values with MDX for the upper-levels.

Consider the following (natural) hierarchy, data and expected outcome:

(It might look a bit weird, but icCube allows to have the leaf empty for SUB013 and SUB014.)

As you can see in the desired outcome in the picture above, I expect "voila" to be displayed on SUB015.

But, I can not get it to work. See the outcome I get with MDX:

I have the following issues:

the value is empty (I have used the no aggregation type on text)
another observation is that also the amount is empty for a no aggregation type

Is this solvable, somehow?

(enclosed as a snippet - not runnable - the schema I used, which you can upload in your instance of icCube)

In icCube a node value, even if leaf, can be the result of an aggregation over multiple facts rows. When you specify, NO_AGGREGATION, as aggregation method the NULL is returned if more than one single row is in play.

For you example as SUB015 has a child with value, CHILD003. And the dimension is defined with 'Fact Aggr. Type' as 'Members and Ancestors'.

Two solutions :

1) Add a Dimension member property that is retrieved using a calculated member.

2) Use a dimension with 'Fact Aggr. Type' as 'Members' but you will get wrong cost.
