After the ARIS model was transferred from ARIS to PPM, every new or modified process instance of an eligible process type (that is, a process type for which an appropriate conformance measure is defined) is automatically checked for conformance during PPM import.
A recalculation of old instances with reference to the new model requires running PPM import with option -keyindicator new (or -typifier new, which implies -keyindicator new).
For details on how to run PPM import, see the runppmimport command line tool in the PPM Operations Guide.
