Test case error message type SMDT : how to define 'categorization' & 'Priority' with new values.

Hi,

For Test case error message type SMDT :

1) I need to populate field 'categorization'.  ( should this be done from SAP Web Client only ?)

2) I need to populate field 'Priority' with new values. (I have changed values in table: SCPRIO using SM30 and also have checked this using SPRO in "MAINTAIN PRIORITIES OF DATES" in area "Application Incident Management (Service Desk)" and area "Settings for Activities" )

The new  values are NOT showing up after making the changes when creating new SMDT message.

We are using SAP Solution Manager 7.1

Thanks.,
