Step 2: Defining the Set of States of the Workflow

In this step, you will define the set of states for the workflow of a repair work order. The workflow state is determined by one of the fields of the record, which is usually the Status field. Therefore, you need to define the set of states that corresponds to the set of statuses that a repair work order can have.

According to the customization description, which is available in Business Process Overview, a repair work order can have the following statuses:

• On Hold (the WorkOrderStatusConstants.OnHold constant)
• Ready for Assignment (the WorkOrderStatusConstants.ReadyForAssignment constant)
• Pending Payment (the WorkOrderStatusConstants.PendingPayment constant)
• Assigned (the WorkOrderStatusConstants.Assigned constant)
• Completed (the WorkOrderStatusConstants.Completed constant)
• Paid (the WorkOrderStatusConstants.Paid constant)

To create the set of workflow states, do the following:

1. In the Constants.cs file, make sure that the constants for the Status box are defined as shown in the following code. These values will be used to indicate the states of the workflow.

       //Constants for the statuses of repair work orders
       public static class WorkOrderStatusConstants
       {
           public const string OnHold = "OH";
           public const string PendingPayment = "PP";
           public const string ReadyForAssignment = "RA";
           public const string Assigned = "AS";
           public const string Completed = "CM";
           public const string Paid = "PD";
       }

2. In the RSSVWorkOrderEntry_Workflow class, define the Constants region and the public static class inside it, as the following code shows.

           #region Constants
           public static class States
           {
           }
           #endregion

3. In the States class, define the constant string values that correspond to the repair work order statuses, as the following code shows.

               public const string OnHold = WorkOrderStatusConstants.OnHold;
               public const string ReadyForAssignment =
                 WorkOrderStatusConstants.ReadyForAssignment;
               public const string PendingPayment =
                 WorkOrderStatusConstants.PendingPayment;
               public const string Assigned = WorkOrderStatusConstants.Assigned;
               public const string Completed = WorkOrderStatusConstants.Completed;
               public const string Paid = WorkOrderStatusConstants.Paid;

4. In the States class, define the classes for each state of the workflow, as the following code shows.

               public class onHold : PX.Data.BQL.BqlString.Constant<onHold>
               {
                   public onHold() : base(OnHold) { }
               }
   
               public class readyForAssignment :
                 PX.Data.BQL.BqlString.Constant<readyForAssignment>
               {
                   public readyForAssignment() : base(ReadyForAssignment) { }
               }
   
               public class pendingPayment :
                 PX.Data.BQL.BqlString.Constant<pendingPayment>
               {
                   public pendingPayment() : base(PendingPayment) { }
               }
   
               public class assigned : PX.Data.BQL.BqlString.Constant<assigned>
               {
                   public assigned() : base(Assigned) { }
               }
   
               public class completed : PX.Data.BQL.BqlString.Constant<completed>
               {
                   public completed() : base(Completed) { }
               }
   
               public class paid : PX.Data.BQL.BqlString.Constant<paid>
               {
                   public paid() : base(Paid) { }
               }
