Returns lifecycle



RMA request (return) is modeled as RmaReturn entity in VCF data model. RmaReturn is integral part of an Order. RmaReturn may be created for an Order of state Completed. A return life cycle is divided into separate distinct states (enumeration):

public enum RmaRequestStatus
  Complete = 1,
  Canceled = 2,
  AwaitingStockReturn = 4,
  AwaitingCompletion = 8

RmaReturn is always in one of enumeration's RmaRequestStatus states. If exact enumeration mach wouldn't be found then it's considered to be in a state of AwaitingStockReturn. State changing is controlled by StateMachineBase implementation (RmaRequestStateMachineImpl class). This actually implements the state diagram depicted below and controls state transitions.

Create return

Return is created as a part of an order. It's initial state can be AwaitingStockReturn or AwaitingCompletion. Return amount is calculated in external workflow, which is accessible trough service.

public Order CreateRmaReturn(Order order)
  CurrentOrder = order;
  var rmaRequest = CreateEntity<RmaRequest>();

  // fill the RmaRequest properties, add/remove returning items using AddReturnItem / RemoveReturnItem respectively

  // setting correct status is essential
  if (rmaRequest.IsPhysicalReturnRequired)
    rmaRequest.Status = RmaRequestStatus.AwaitingStockReturn.ToString();
    rmaRequest.Status = RmaRequestStatus.AwaitingCompletion.ToString();

public void AddReturnItem(LineItem lineItem, decimal returnQuantity, string returnReason)
  var returnItem = RmaReturnItems.FirstOrDefault(x => x.RmaLineItems[0].LineItemId == lineItem.LineItemId && x.ReturnReason == returnReason);

  if (returnItem == null)
    var rmaLineItem = CreateEntity<RmaLineItem>();
    rmaLineItem.LineItemId = lineItem.LineItemId;
    rmaLineItem.LineItem = lineItem;

    returnItem = CreateEntity<RmaReturnItem>();
    returnItem.ItemState = RmaLineItemState.AwaitingReturn.ToString();
    returnItem.ReturnReason = returnReason;


  returnItem.RmaLineItems[0].ReturnQuantity += returnQuantity;
  lineItem.Quantity -= returnQuantity;

  if (lineItem.Quantity == 0)


public void RemoveReturnItem(RmaReturnItem returnItem, decimal returnQuantity)
  returnItem.RmaLineItems[0].ReturnQuantity -= returnQuantity;
  if (returnItem.RmaLineItems[0].ReturnQuantity <= 0)

  var availableLineItem = AvailableForReturnLineItems.FirstOrDefault(x => x.LineItemId == returnItem.RmaLineItems[0].LineItemId);
  if (availableLineItem == null)
    availableLineItem = _deletedLineItemList.FirstOrDefault(x => x.LineItemId == returnItem.RmaLineItems[0].LineItemId);
    // undelete

  availableLineItem.Quantity += returnQuantity;

// Recalculates current Return's amounts: fees, subtotals, totals, etc.
private void Recalculate()
  var orderService = ServiceLocator.Current.GetInstance<IOrderService>();
  var result = orderService.ExecuteWorkflow(RecalculateWorkflowName, CurrentOrder);
  CurrentOrder = result.OrderGroup;

Transition to AwaitingCompletion state

State transition AwaitingStockReturn --> AwaitingCompletion is initiated upon RmaReturn RmaLineItems quantity change:

private void RecalculateRmaRequestStatuses()
  //if all lineItems physically returned to stock need change status 
  //to AwaitingCompletion
  var retVal = InnerItem.RmaReturnItems.All(x0 => x0.RmaLineItems.All(x => x.ReturnQuantity == x.Quantity));
  InnerItem.Status = retVal ? RmaRequestStatus.AwaitingCompletion.ToString() : RmaRequestStatus.AwaitingStockReturn.ToString();

where InnerItem is instance of RmaReturn.


RMA request can gain status of Complete when there exists a state transition to RmaRequestStatus.Complete. Steps to complete:

  1. If RmaReturn.ReturnTotal > 0, then "Create Refund" process with ReturnTotal amount should be initialized. 
  2. If previous step completed successfully, then set the status: RmaReturn.Status =  RmaRequestStatus.Complete.ToString();
