We've got a standalone Invoice with an item with an RRR. It generated the corresponding Revenue Arrangement. We realized that we used the wrong item. It should have been an item that is marked Direct Revenue Posting. We deleted the Revenue Arrangement. We removed the original item line then added a new item with Direct Revenue Posting on the Invoice. Hence, there should be no Revenue Arrangement anymore. However, the orphaned Revenue Element is still there. How do we get rid of it? Deleting the source transaction will not work since they are no longer linked anyway.
