Add Field Node with Node Action GetRequiredValue

To Add a Field Node with the GetRequiredValue Node Action

1. Right-click on the Table Node and select Add Field Node | GetRequiredValue. The Add Field pop-up window will be displayed.
2. In the Add Field window:
   1. Select Field Name from the Field Name drop-down menu. This drop-down menu lists all of the columns with the Used property of the parent Table Node set to True.

You can select the desired DAL by scrolling to the desired entry or by typing the first letters of the DAL Component (this highlights the entry that starts with that letter). When the DAL Component is selected, the SelectBy methods and columns (in the FetchFieldName drop-down menu) available for the DAL Component are listed.
   3. In the DAL select methods grid, choose the SelectBy method.
   4. Select FetchFieldName from the FetchFieldName drop-down menu and click OK.
