Dynamic ALV + deep structure

Hi Experts,

I have a requirement to use dynamic ALV with the color table.

The number of ALV columns depend on the Time Horizon selected

i.e 10Days will display 10 columns or 14Days will display 14 columns

How do you dynamically create an internal table with a deep structure?

The deep structure is required because I need the color table in the field catalog to color individual cells of the ALV!

Any ideas how to do this?
