How to identify processing type of a Varibale.

Hi Experts,

I need some information where i can see what kind of processing type is used in variables.

In my case there is a selection, In that selection keyfigure has been restricted to a characteristic and there is a variable for that characteristic.

I am unable to understand what kind of processing type is used for that variable. When I double click on that variable its now showing any thing.

Please help me in this.

Thanks & Regards,

Ravi
