3484375 - Subsequent Credit Is not the Same as Credit Memo

Scenario example:

In purchase order, 10 pieces of products are ordered. Then 3 pieces should be returned. A Return to Supplier is created and a Credit Memo is expected. However, only 2 pieces are included in the Credit Memo. The third one is created as a Subsequent Credit Item. As a result, the quantity that credit memo should be created is still "1", which is expected to be "0".
