Hi,mikolaj_rudnik 

Regarding the issue you raised, my solution is as follows:

1.Regarding your reference to reaching the maximum number of entity or relationship warnings, our analysis suggests that your model may be beyond the scope of the Q&A function due to its size and complexity. Power BI automatically creates language patterns based on the data set structure, but its processing power is limited. As you have tried, editing the language pattern directly in search of improvement is not guaranteed to work if the problem is rooted in the complexity of the model itself.

Here is the relevant documentation:

2.Second, you can optimize the size of your data model:

Move unnecessary tables around on demand and store data using the direct query storage pattern.

View measure, relationships, and performance of visual objects: Review metrics in models, relationships between tables, and performance of visual objects. Make sure they are designed to be efficient and optimized.

Use variables to improve performance and troubleshooting: Using variables in DAX expressions can improve performance and help troubleshoot problems. Variables can store the results of calculations to avoid double calculations.

 

3.Finally, you can also try using incremental refresh. An incremental refresh strategy for partitioning tables, where only the latest imported partition is refreshed and another DirectQuery partition can be used for live data, can significantly reduce the amount of data that must be refreshed. At the same time, this policy ensures that the latest changes to the data source are included in the query results.

Here is the relevant documentation:
