Step 4: Adding the Skip Condition

The Postponed workflow state should be skipped if no discount is being applied to the invoice—that is, if the Document Discounts box is 0.0 on the Invoices (SO303000) form. In this step, you will define this condition by doing the following:

On the Invoices (SO303000) form, learn the field name of the Document Discounts box by using the Element Inspector tool. The field name is CuryDiscTot. The field is defined in the ARInvoice DAC.

In the SOInvoiceRepairOrder_Workflow class, define the condition, as the following code shows.

        #region Conditions
        public class Conditions : Condition.Pack
        {
            public Condition DiscountEmpty => GetOrCreate(condition =>
              condition.FromBql<ARInvoice.curyDiscTot.IsEqual<decimal0>>());
        }
        #endregion

Add the necessary using directive, as the following code shows.

using static PX.Data.WorkflowAPI.BoundedTo<PX.Objects.SO.SOInvoiceEntry,
  PX.Objects.AR.ARInvoice>;
using PX.Objects.CS;

Create an instance of the Conditions class in the static Configure method, as the following code shows.
```
            var conditions = context.Conditions.GetPack<Conditions>();
```
Save your changes.
