Selection not possible via Nav Attr

In my InfoCube, I have turn ON the Nav Attr 0Plant, which is an attribute of the Material Master. Activated the InfoCube.

Now, in RSA1, I right-click this InfoCube and click on Display Data.

I selected this Nav Attr and InfoObject Material Master.

I entered Plant 1500 in Nav Attr field and click Execute. Funny thing is I donu2019t get any result.

If I enter the Material Master 1000058948, and click Execute, I see the Material Number and Plant 1500 on the screen.

Why I canu2019t use the Nav Attr plant to select the data? Is this bug?

Any idea?
