Do you have an estimated date for implementing this?

nope, it's not possible for assets. Only for tickets...

Example: Make entering the serialnumber of a new Computer mandatory.

I made a status "decommissioned" for this. Unfortenatly it's a bit dirty because I have to filter every search and for example some views off the softwarepanel (versions/installed) are counting them because it's no search which i can filter.

Additional a function to make fields mandatory would be great.

It's not only the core integration. The basic problem is that there is missing a option for editing existing fields, making them mandatory or hide them and adding new Menus with items. The actual solution is not very trusty for productive usage.
