The following business rules govern Excel Add-In exports for projects using version control.

* When you upload a new requirement or test, it is created in ALM, with a checked in status.
* When you upload an existing requirement or test that is checked in, it is automatically checked out
and then checked in during upload. ALM adds a comment to the version history specifying that the
requirement or test was updated by upload from Excel.
* If you upload an existing requirement or test that is checked out by the same user that you use to
upload the data, the data is uploaded. If the requirement or test is checked out by another user, the
upload fails and an error message is displayed.
