Table Maintenance Generator v/s Maintenance View

Hello SDNers,

I am into a new project & in this system the developers have created Maintainence View for all Z-tables. None of them have a Table Maint. Generator(TMG) defined. The tables are maintained through custom transactions associated with the views.

I am just thinking what advantage do Maint. Views have over TMG?

Any inputs will be appreciated.

BR,

Suhas
