• Message number: 437

• Message text: Request &1 is assigned to a different client

What causes this issue?

Request/task "&V2&" cannot be linked to or merged with request/task
"&V1&" because they are not assigned to the same logon client.
Client for request/task "&V2&": "&V4&" OK
Client for request/task "&V1&": "&V3&" not logon client !

System Response

The function was terminated.

How to fix this error?

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.
