Why the receiving side may not apply it
The payment may have reached the receiving side but not been applied. That can happen when the account name, IBAN, SWIFT/BIC, address, reference, or beneficiary bank requirement does not match cleanly.
You are in the right place if the supplier bank says beneficiary details are incorrect. The payment may have reached the receiving side, but that does not mean it has been applied, released, or matched to the beneficiary.
Beneficiary-side problems turn a payment into an exception case. The funds may already be at or near the receiving bank, but the bank cannot confidently apply them to the intended account or party. For this case, gather supplier bank message, original payment instruction, correct details, UETR, and account proof. The next decision is whether the receiving bank can release or repair it, or whether recall or investigation is safer.

Compare supplier bank message, original payment instruction, correct details, UETR, and account proof. Small differences can change whether the bank releases, repairs, rejects, or asks the sender bank for an amendment.
This becomes investigation when the receiving side has the funds but will not apply them. Recall becomes relevant when the beneficiary or account is wrong and the money needs to be pulled back before it is credited or moved onward.
