hi Bobby,
Yes, but it doesn't always mean that the document in ECC was deleted. There could be cases where the document exists in ECC and GTS. But the linkage/reference is missing in GTS.
So, basically the reorganization is to identify the list of documents in GTS which doesn't have a reference/linkage to a document in feeder system. Once you have the list of documents in GTS, you can delete those customs documents here and retransfer the corresponding document from feeder system(if the problem was with linkage). If the case was the feeder system doc deleted, you can recreate the same and customs document will be created in GTS automatically.
