A SDD Return results in two (sometimes three - see below) transactions within your LW environment:
• The return transaction (Method = SDD/Type = Outgoing/Status = Success) located in the client payment account on which the original transaction has been credited, with the SDD Return reason code & description (more info in the dedicated topic) in the Comments field and the original transaction ID in the Original Transaction field. In case the balance of the concerned client payment account is not high enough for LW to debit the return transaction, a P2P is automatically performed from your merchant payment account (SC) to the concerned client payment account of the complementary amount before the SDD return transaction is debited
• The transaction corresponding to LW SDD return fees (P2P from your merchant payment account to LW payment account of the amount of fees as defined in your contract)
SDD return transactions can be obtained through the API or consulted/exported manually from your LW Back-Office (Operations > Overview, filters Method = SDD/Type : Outgoing/Status = Success, then select the chosen period and hit Filter).
