Not able to delete badi Implementation

Hi,

I have created an implementation which I am no longer using. I want to delete this implementation. I cant delete the badi as I am using standard badi RSU5_SAPI_BADI. I want to delete a particular implementation under this badi. I have already tried to delete using a FM SEO_CLASS_DELETE_COMPLETE but it didnt help mu much on this.

Please suggest

Thanks
