Macro Function CELL_BG() or ROW-BG() not working

Hello SAP experts,

We have a requirement where Planners want to Flag an item in the Planning book and follow up this flagged material sometime in the next month after the Forecast run.

They wanted to get an Alert of that material saying that this material is flagged.

I tried to create a macro which will color a key figure row from buckets 01/2015 to 03/2015 in the planning book, when they want to flag a particular material they can just click on the macro button to color those cells (from 01/2015 to 03/2015) . I have created another macro which will generate an alert ( Item is Flagged) based on the color of those 3 cells (01/2015 to 03/2015) .

But, the problem I am facing is , when I click on the macro button it is coloring the cells from (01/2015 to 03/2015) . But, when I hit SAVE button , the Color is gone.

I tried ROW_BG() macro function as well, I have the same problem with this as well.

FYI: I don't have any  macros set in Default or Level change or Start or Exit..

Not sure why the Color is lost for the cells when I hit SAVE. See below macro that I wrote.

Please help.

Thanks,

SV
