SOST- Deletion of transmission request in background

Dear All,

I have configured the Alert management system to forward the CCMS alerts to the external communication method like SMS and email.

In the Transaction code SOST, I want to delete the "transmission requests" periodically in the back ground.

That is I would like to automate it instead of deleting the transmission request manually.

Can any one help me out in achieving this.

Thanks and Regards,
