According to the instructions of Annex 3 - S.06.02 – List of assets (reported below), we shall add the ISO 4217 alphabetic code of the currency to the Asset ID code only in cases of assets issued in two or more different currencies.

However, the document seems not specifying how to populate the field in case of assets with same ISIN code and same currency but issued in different country of custody. Should we report 2 different row with the same asset ID code, as the country of custody, quantity are not the same. Is it allowed to report same isin as Asset ID code, due to different country of custody.
