The ZAttributeCalculatorFunctionCount attribute calculator writes the number of function nodes in the EPC to a configurable attribute at the process level.
Example
<calcattr name="AT_FCT_COUNT" type="PROCESS" >
<calcclass name="com.idsscheer.ppm.server.keyindicator.
attributecalculator.ZAttributeCalculatorFunctionCount">
</calcclass>
</calcattr>
There is no calculation for aggregated EPCs.
Further information on How to handle large EPCs is available in the documentation PPM Data Import.
