ALV with ONE itab But with 4 Different Result Sets

Hi,

I have a req like I need to display data of only one itab but with 4 differnt Result sets.

I have 5 options on selecton-screen. Among first 4 options I can choose only one. So if I select option 1 then it will load itab data accordingly and display, same applicable for 2 3 and 4.

But 5th one is combination of 4 options. I need to display itab combined data of all 4 options.

The 5th option output wud be like:

Heading: option1

itab data

Heading: option2

itab data

Heading: option3

itab data

Heading: option4

itab data.

Can any one suggest a way acheive this.

Thanks in advance.
