Helper IIIImproving report query performance
Hi,
Thanks for the solution rajendraongole1 offered. and i want to offer some more infotmation for user to refer to.
hello YoungLearning
for the cardinality relationship, the model won't provide flexibility in the ways you report visuals filter or group
And the connection mode is direct query mode, it has limitations for direct query mode, you can refer to the follwing link.
When we have two tables that have many-to-many relationship, we often create a bridge table to create a one-to-many relationship among them, you can refer to the following picture.
2.For the cross filter, the data mode is direct query, then using bith filer direction, you can apply the filters by propagating the filter context to a second related table on the other side of a table relationship. you can refer to the following link.

And you can refer to the following link about the advantage of star schema.

Super UserHi YoungLearning - Basically, One-to-Many : This is the most efficient and commonly used cardinality in star schemas. It optimizes query performance because it aligns with typical analytical patterns.
try to maintain star schema design for simpler relationships improve query performance by reducing the complexity of the model.
Aggregate data at the source or during the import process to reduce the volume and granularity of the data in your Power BI model.

Hope it helps.

Appreciate your Kudos!!
YoungLearningSo the cardinality cannot be further reduced, that explains...
So cross filter is the most appropriate answer here?
