To define the Unit Load components:

1. Click Select in the Unit Load component section.
2. When the dialog box appears, select the packaging type from the drop down menu that will be used to ship the previously selected base container.
3. If that packaging type is currently sourced from only one vendor, the packaging item field will automatically be populated for you.  If that packaging type is sourced through more than one vendor, choose the vendor specific packaging item number from the drop down list.

Note: After selecting your unit load the appropriate dimensions will be populated on the bottom of the PDS.

4. Click Update to save unit load selection and return to the PDS.
5. Continue to next step. See Update as Shipped Summary.
