Step 2: Extending the ARDocStatus class

Before you add the Postponed state to the workflow, you need to add a string constant and class to the extension of the ARDocStatus class. You also need to add a corresponding value to the field that holds the record's status on the Invoices (SO303000) form. Do the following:

1. In the SOInvoiceRepairOrder_Workflow.cs file, extend the ARDocStatus class by adding the following code.

       public class ARDocStatus_Postponed : ARDocStatus
       {
           public const string Postponed = "O";
           public class postponed : BqlType<IBqlString, string>.Constant<postponed>
           {
               public postponed()
                   : base("O")
               {
               }
           }
       }

2. Add a combo box value to the Status box on the Invoices (SO303000) form by calling the WithFieldStates method in the lambda expression for the UpdateScreenConfigurationFor method, as the following code shows.

                   .WithFieldStates(fs =>
                   {
                       fs.Add<ARInvoice.status>(state =>
                           state.SetComboValue(ARDocStatus_Postponed
                             .Postponed, "Postponed"));
                   })

3. Save your changes.
