Change KeyFigure description via Macro

Hi,

I looking for to change KeyFigure descriptions via a macro.

I know that the Keyfigure description can be changed by within RSA1 or witihn the Planningbook settings --> Key Figure Attributes.

But I need a way to change the Keyfigure description dynamiclly based on certain selection criteria.

So far I only found a workaround via the ROW_TOOLTIP function. Means KeyFigure description wll not changed, but within Tooltip I can show a diffrent name.

Is there any macro function to change the KeyFigure description.

Thanks,

Mario
