How to reduce the load when linking star schema fact tables

[Anonymous]

In the star schema shown below, it was possible to make one of the fact tables bidirectional in order to link the fact tables without the key of the master table. However, as the number of data and parameters increases, the calculation of the Power BI measure becomes very heavy. I would like to know how to deal with this problem.

thank you very much.

@Anonymous , bi- directional join means if any filter that impacts fact will also recalculate dimension values on use on-page.

This means all slicers will be filtered based on any change.

I understand. It is unavoidable that the filters between these fact tables become heavy.

Thank you for answering.
