Cancelling a book out

You can cancel any book outs that you have performed. If your security group's access rights permit it, you can also cancel book outs that have been performed by other users.

To cancel a book out and forcibly unbook a destination project, do the following in the master project:

On the Project tab, in the Data group, click the Book In/Out dropdown and select Cancel Book Out. The Cancel Book Out dialog appears.
Select the check box to the left of the destination project you want to forcibly unbook.
Click OK. The connection between the master project and the destination project is broken and the project view icons of the charts and summary groups that were booked out into the destination project return to normal.

Once you have cancelled a book out, there is no way of booking the destination project back into the master project, so you can delete the destination project.
