Advanced manufaccturing - update of assets on work benches

Hello,

I would like to mass update asset on work benches,
When trying this, I executed following scenario:
1) Added an asset to a work center
2) Checked to which work bench operation the work center was linked
3) did the mass update of "AM Workbench Asset Mass Update"
4) checked if the new asset was assigned to the work bench

This scenario fails, since the asset was not assigned to the work bench, did I do something wrong here?

I followed following instructions from the advanced manufacturing administration documentation:

Mass Asset Assignment After work bench records are created, you must associate them with one or more assets from the affiliated work center. Use the mass update feature to assign all of your work center assets to a set of work bench records. For more information, see the help topic Mass Changes or Updates.
