I would like to make an overview based on data from various elements.
I would need to enrich this overview with a custom calculation.
e.g. the % based on 2 columns
How do I do this?

Hi Mieke,
Your use-case is indeed a perfect fit for the custom operator feature GQI provides. A custom operator lets you manipulate GQI data in any way you want. Currently there is only internal documentation on how to create one: https://devdocs.skyline.be/GQI/User_Definable/Operator/Tutorial1/
Using a custom operator in the dashboards/low-code apps is at the moment still behind the GenericInterface softlaunchflag.

I believe you would aggregate all required data in one table with a GQI query, and then apply a custom GQI operator for whatever logic you require.

Documentation update:
You can now also find documentation about the custom operator feature in the official DataMiner Docs: https://docs.dataminer.services/user-guide/Advanced_Modules/Dashboards_and_Low_Code_Apps/GQI/Extensions/GQI_Custom_Operator.html
This documentation includes two tutorials (Creating a minus operator & Optimizing your custom operator).
