Patch Updation error

Hi,

While doing the patch updation,the power was gone.After restarting the server and logging to the SAP GUI an error message is occuring "Status 0020 of the user interface SAPMSYST missing" at the start of the SAP menu. Also it is saying that You are not authorised to use Transaction SU01 or STMS or SPAM or say not even one transaction.

Bye,

Suri
