System Object Access uses the List Nonprogram Messages (QMHLSTM) i5/OS™ API to retrieve attributes for messages.
The possible special values are the same as those that are documented in the i5/OS APIs: Message Handling APIs topic in the iSeries™ Information Center.
CWBSO_SetListFilter accepts the special values that are supported by the List Nonprogram Messages (QMHLSTM) API for Severity Criteria. In addition, a 10-character user name may be supplied, by specifying the CWBSO_MSGF_UserName filter ID. “*CURRENT” may be used to obtain a list of messages for the current user.
