The function could not be completed and is terminated.
Report the error to the system administrator.
The action is based on the value specified in caller_name.
If caller_name specifies "IEFUSI" then the Application Performance Analyzer Step Initiation Exit is back leveled with the version of the Application Performance Analyzer started task. Follow the instructions in the Application Performance Analyzer Customization Guide to upgrade the IEFUSI exit.
If caller_name specifies "ISPF CMD" then upgrade the Application Performance Analyzer/ISPF interface.
If caller_name specifies "SPX" then one or more members of the Application Performance Analyzer sysplex group is back leveled. Ensure that all members of the group are at the same Application Performance Analyzer version or higher.
