At the moment, calculated measures are only supported for JSON and CSV datasources. Do you have plans to support it for Mondrian and SSAS, too?
Thank you for your question.
For Mondrian and SSAS data sources we kindly suggest defining calculated measures on the server-side.
Please let us know if you have further questions.
Well, the calculated measure is created by the user, so it cannot be defined in advance on the server-side.
Thank you for your feedback.
For now, the only way to set calculated measures for the Mondrian data source is to define them in advance on the server-side.
In case you require user-controlled creating of calculated measures, we can only recommend using one of the data sources which support the feature by default.
