Revenue Recognition billing based

Hi Experts,

We are implementing Revenue Recognition where once a billing document is generated, it creates a Revenue Recognition block. This process we were able to implement it. However when posting through F-28 transaction, we need to automatically remove the revenue block placed in vbreve. Any body has any idea as how to handle the 2nd process of removing the Revenue recognition block. Any user exit or badi or BTE for the same anyone is aware of please.

Thanks
