Deleting SFCs permanently

Dear All

I am in a situation where I need to delete SFCs from the database permanently/completely as opposed to assigning a different status which is what ME does. This is due to the fact I do have a lot of them by means of nightly planning and transfer from SAP ERP. The Shop Orders do get deleted from the WIP db, no problems there, but SFCs are retained with just a different status assigned.

Is there a way to delete SFCs other than manipulating manually on db-level?

Thanks & Regards,

Stefan
