Hi, In an integration for shippments I get shippments for several orders and when some orders has been processed I get below Concurrency error, and the site restarts. The error occures within: delivery.SetDeliveryStatus((short)DeliveryState.Delivered, securityToken); The delivery status is updated, the Payment is captured, but the orderstatus is not updated to completed. When running the same order again, it works. —Error— Exception in Litium appId=/LM/W3SVC/1/ROOT type=Litium.Foundation.Modules.ECommerce.Data.ConcurrencyException message=Delivery (db9f64c1-1a12-4973-82be-6597aaf420f1) has already been changed in the database.

Hello… “jenni73” 😇, Do you update the order as well close to this code? If so in what order do you update your entities (order and delivery)? ---

> [@MartinBrandt](#): > > e to this code? Halloj Martin;) No, I update the delivery with: delivery.SetActualDeliveryDate(DateTime.Now, securityToken); delivery.SetTrackingUrl(shipmentNumber, securityToken); delivery.SetDeliveryStatus((short)DeliveryState.Delivered, securityToken); When the error occur, ActualDeliveryDate and TrackingUrl is set and: DeliveryStatus=Delivered, PaymentStatus=Paid but Orderstatus=Processing(as before the job starts) When everything works, after SetDeliveryStatus, DeliveryStatus= Delivered, PaymentStatus=Paid, Orderstatus=Complete. I do not update the order directly in this job, only via the delivery. //J ---

Do the update with the carrier instead, something like ```cs var carrier = delivery.GetAsCarrier(); carrier.ActualDeliveryDate = DateTime.Now; carrier.TrackingUrl = shipmentNumber; delivery.SetValuesFromCarrier(carrier, securityToken); delivery.SetDeliveryStatus((short)DeliveryState.Delivered, securityToken); // Should be executed after the values are set, that will invoke state transition engine. ``` ---

Hi @patric.forsgard, I still get the problem with ConcurrencyException with the code var deliveryCarrier = delivery.GetAsCarrier(); deliveryCarrier.ActualDeliveryDate = DateTime.Now; deliveryCarrier.TrackingUrl = shipmentNumber; delivery.SetValuesFromCarrier(deliveryCarrier, securityToken); ``` delivery.SetDeliveryStatus((short)DeliveryState.Delivered, securityToken); ``` it looks like the problem only occurs with Klarna V3 payment provider, and when running in a Try-Catch statement, the next order works, if its not Klarana V3. My Conclusion is that Klarna does something within the delivery.SetDeliveryStatus((short)DeliveryState.Delivered, securityToken) statemend, like sets the deliverystatus to something else first, it does the capture and then tryes to set de delivery to delivered… however the problem remains ☹
