Calculate with attribute

Hi ,

We want to use the attribute (key figure) value (i.e Price value from 0MATERIAL) create a new calculated Key figure following instructions in How to ..papers in SAP site . when i use the 0material in drilldown it shows the proper values for this , but as i remove material from drill down & use any other

characters (ex Profit center) the CKF no more shows any values .

But in How to paper it is said to work fine at any level ..

could any one throw more lights on this issue .

Thanks
