To monitor critical times in individual process instances as part of the Early alert system, you can define special time dimensions in the measure configuration. These time dimensions are identified by the earlyalert attribute having the value yes (CTK: Enable the Early alert check box). For all other time dimensions, this attribute has the value no by default.
To optimize performance, save critical time dimensions that you defined for the Early alert system as incube time dimensions. For better differentiation, the name of the dimension (name) should begin with the prefix CRIT_.
As critical time dimensions are only calculated internally at the process instance level, the internal attribute must have the value yes (CTK: enable the corresponding check box in the Internal column) and the dimtype attribute must have the value PROCESS (CTK: Select the value PROCESS in the Usage column). Otherwise, an error message is output when importing the configuration.
Time dimensions from the Early alert system are internal dimensions and therefore are not displayed in the dimension list in the navigation structure. For this reason, the assignment to a dimension group is illogical and therefore ignored.
