Engineering Release (XEN) - add Mass and Volume into Attributes coming from measured CATIA values

In the Engineering Release (XEN) there are 2 attributes "Mass" and "Volume", which I would like to fill with values from 3DX CATIA.

In 3DX-CATIA, the weights were declared via BI Essentials.

My expectation was that these values would appear in the Mass column.

What do I have to do to fill mass and also volume with values?
