Method ActivateRevision(RevisionNr: string)
Description
There is always one active revision from the list of revisions. With this function a revision can be activated, which means that the revision is immediately available through the ActiveRevision property so the user does not have to look it up on the list every time. Note: activating a revision is not equal to making it valid!
RevisionNr
Technical key value of the revision to be activated from the list.
Result
If the revision was successfully activated the result is TRUE; it is FALSE in all other cases.
