Where is used "member_description" ?

[tibo-k3]

Hi everybody.

When I create a Regular Dimension, I implement a "member_description", however, I don't where it's used after.
In fact, in Analysis Studio, there is only the member_caption displayed, even when I drag over the item with the mouse... And the User Guide only gives "Returns the description for a member" as description !

So, question : where it's used, or displayed, the "member_description" in Analysis or Report Studio ?

Thank you !
