Hi,
I wouldn't search where the hierarchy is used. You can create your own querry to check the changes.
The simplest way to check if a hierarchy is updated is to contact with a person who updates it on ECC side and ask what was changed most recently. I you see the same changes on BW side you are sure updating is working all right.
Your hierarchy is updated manually or in process chains ?
