Editable Hierarchial ALV

Hello all..

I have a requirement where i need to use an editable alv to display the details.

But in the alv display 1st row should display entries from 1 table and second row should show entries from another table.

So is this possible with normal grid display or do i need to go for hierarchial sequential display?

A piece of code would be more helpful.

Any pointers to my query would be highly appreciated.

Thanks in advance.
