Can i move a function source to a internal table?

Hi, Experts..

I want to get a internal table that has a function source.

In case of report program, generelly we can get a internal table about report source as follows.

READ REPORT xxxxx  INTO itab.

But i don't know how to get a internal table about function source.

Can i get it?

Help me please. Thanks.

Regards.
