How to re-create default stored procedures on AX DB?

Hi All,

I have an AX DB that was missing the dbo.getNumInternal stored procedure. We have already fixed this by copying over from another DB but I have 2 questions-

1. Any ideas on how this stored procedure could have disappeared?
2. Is there a way to automatically re-create the default stored procedures? Technet claims that you can do so by re-initializing the modelstore (axutil schema) but it didn't seem to work for me...

Thanks!
