Report works sometime, sometimes data is missing

[DavidGM]

Hi, I dont get any refresh error,  but at some times the report doesn't show all data. Error is sporadic, after the refresh data might show up but than I can see data missing in some other tab/ filter.

What can be the reason behind this error.

Thanks

Hi, @DavidGM 

check your schedule refresh timings match with the data source update timings. Additionally, 

1. Check data source connectivity for any issues.
2. Review data transformations and query folding.
3. Verify data model relationships and filters.
4. Check DAX measures and visual-level filters.
5. Consider data volume and resource limitations.
6. Review Power BI service settings and refresh logs.
