Filtering data in the BusinessProcess

• Add a parameter to the Run method of type Number called "OrderId" and filter according to it:

public void Run(Number OrderId)
{
    Where.Add(Order_Details.OrderID.IsEqualTo(OrderId));
    Debug.WriteLine("Before the Execute");
    Execute();
    Debug.WriteLine("After the Execute");
} 

• Run the controller, using the "Controllers" developer tool
• Note that now it asks for an 'OrderId' to use as a parameter to the 'GetOrderStatistics' BusinessProcess
• Review the Life-Cycle using the output window, for a specific order
• Note that the 'OnSavingRow' event doesn't get executed, since we didn't make any change to any row.
• Remove all the Life-Cycle related code, to get a simple Business Process

public class GetOrderStatistics : BusinessProcessBase
{
    readonly Models.Order_Details Order_Details = new Models.Order_Details();

    public GetOrderStatistics()
    {
        From = Order_Details;
    }
    public void Run(Number OrderId)
    {
        Where.Add(Order_Details.OrderID.IsEqualTo(OrderId));
        Execute();
    }
}
