Make location field mandatory so that the user will not forget it, otherwise the prod order will not be used in the material planning for that location.

This will also be solved by the more general solution:

or

I think this idea om being able to set a field as mandatory is no brainer.

It helps improving data and makes processes more efficient.

So I dont understand why it is not on the roadmap yet.
