The Invisible measures group contains all measures that are only displayed in the measure list when the group is actually selected. Only then are they available in the analysis. The invisible measures are not displayed in the measure lists for all other measure groups. The group of invisible measures is unique and cannot be structured.
Assign measures that are exclusively used as an interim result for the calculation of other measures to the group of invisible measures (<kidef name="..." kigroup="KI_GROUP_INVISIBLE" ... />).
The group is configured in the XML configuration file *_kigroup.xml of the corresponding CTK client template (under PPM installation directory>\ppmmashzone\server\bin\agentLocalRepo\.unpacked\ppm-client-run-prod-<version>-runnable.zip\ppm\ctk\ctk\examples\custom\) by the following element:
...
<kigroupinvisible name="...">
<description language="de" name="..."/>
<description language="en" name=".."/>
