Hi,
you check the authoisation object B_USERSTAT , whether you have any restriction for authorization key in the processor profile?
for example refer here UC00043 - SAP Solution Manager - Security and Authorizations - SCN Wikiin this example shows how to control the access of particular status.
Another use case UC00039 - SAP Solution Manager - Security and Authorizations - SCN Wiki this also similar to your case, check the auth key field too.
please check.
Thanks
Jansi
