Not able to delete key figure

Hi Experts,

I created one Kf, with some exception aggregation.

Then I used this kf in one of the cube, loaded data and done some testing.

Now ,I no longer need this Kf and want to delete the same.But while deleting system is not allowing me to delete this.Its data element is referencing somewhere else.

Error message I'm getting is "

Data Element /BIC/Ozxxxxx (Revised and Active vers.) was not deleted (check references)"

When I done where used of this Kf, the key figure data element is referencing some where else.

like  in /BIC/E table and some view /bic/v100254m etc.

Since I deleted the data in the cube already and there are no aggregates/BIA on this cube not sure why data element referencing to E table and V table(View).

Any help for deleting this Keyfigure?

Thanks
