If you still wish to link the requests/tasks, then proceed as follows:
Contact the person who last changed the request/task &V1&. He has to
log on in your logon client.
He must then choose transaction "SE01" and change the request/task.
A dialog box appears if the change can be made. If he confirms the
entry here, the source client is changed to the logon client.
You can now repeat your function.
