I am doubtful it says that on your bank book when you update the transaction history. It might be on your online statement though 🙂
Unfortunately how you prove the funds came from abroad (especially without doing "Swift code" bank to bank transfers) is not a topic of this group.
You will have to update your bank book then see the transaction code next to the incoming transfers. After that go to your bank, and get a "credit advice" which shows the "money trail".
