How to put Layouts in selection screen for ALV

Dear All,

I have developed an ALV report . The users will create many layouts and save it. The requirement is that:

In the selection screen , they need to get the list of saved layouts and select one from that so that they need not have to select layout after running the report.

That means .. they want to select the layout before running the report.

Hope that you understood my problem and will help me out...

Thanking you,

Shankar
