Maintanence and Help Views!!!!!!

Hello folks,

I have 2 requirements here.

1. I have to create a maintanence view over two tables. For example, I have a table zmara as master data table with material field and zmakt as a material description table. Now I have to create a maintanence view on top of these two tables. If I make an entry for a new material in this view the two tables should be updated.

Can anybody tell me how to do that??

2. How to create a help view??

Points for sure will be rewarded.

Thanks
