Adding an assignable unit

You can only add assignable units if you have designated your project type as a project published for AICC or SCORM. To do so, select Project Options from the Project Setup group on the Design ribbon and select the AICC/SCORM for LMS check box in the Select Project Type window. When this option is set, an assignable unit will automatically appear in the project. If you choose not to select this option and still publish to AICC or SCORM, your entire project will be considered the assignable unit.

When publishing to SCORM, the Assignable Unit will be converted to a SCO (the SCORM equivalent).

To add an assignable unit, in the Project Explorer, select the location within the project into which you want to add the new assignable unit, and do one of the following:

From the Home ribbon, click AU in the Add Structure group.
Right-click in the Project Explorer or in the work area, select New and Assignable Unit.
Type Ctrl+0.

When you add the new assignable unit, an assignable unit graphic appears in the Project Explorer.

The new assignable unit is inserted after the chapter or assignable unit that was highlighted in the Project Explorer.
You can easily re-order items in the Project Explorer by clicking on them, and while holding down the left mouse button, dragging the item within the Project Explorer to its new location. Once the location is chosen, release the left mouse button, and the item will be moved.
The Publisher will attempt to assign a number to the new assignable unit. If the sequence is out-of-order, or if you would like to rename the assignable unit, click the text located next to the assignable unit graphic in the Project Explorer, and enter the new name for the assignable unit.
