Maintenance view variants are partial views of generated maintenance dialogs, i.e. a maintenance view variant restricts the maintenance dialog on which it is based, e.g. to a smaller number of maintainable fields, or uses a more restrictive database selection than the initial dialog. The maintenance view variant has no maintenance dialog of its own, it uses the maintenance dialog on which it is based, including the maintenance screens and all its checks
First read documentaiton in BC - Generate Table Maintenance Dialog :Generate Table Maintenance Dialog, Create a Maintenance Dialog , Initial screen , Maintenance view variants, Create maintenance view variant
