Some versions in an activity change set are not
checked in. The stream cannot be rebased with the current view until work
is checked in. Do one of the following:
- To see a list of checked-out elements, click Find
Checkouts.
- To obtain more information about these elements or to change
their checkout status, right-click an element in the Find Checkouts window
to display the shortcut menu.
- Check in all files. The operation proceeds automatically
when you close the Find Checkouts window.
- To check in versions, click Cancel to
suspend the rebase operation. Then click OK. Check
in the files and restart the rebase operation.
