ALV Layout

Hello,

I am having an ALV list as follows:

Material Description M112005 M112004 M122005 M122004

XXXXX ZZZZZZZZZZZ 20 18 20 19

Now I want to format the ALV layout as below:

Material Description November December

2005 2004 2005 2004

XXXXX ZZZZZZZZZZZ 20 18 20 19

Hope I have made myself clear.

How to do it?

Thanks and Regards,

Pankaj
