Auto date/time is enabled
"Auto date/time is enabled" is one of the performance checks Auditabi runs on a Power BI semantic model. Auto date/time creates one hidden calendar table per date column (n detected). It is a medium-severity finding: the model still works, but results are wrong in some filter contexts, slow, or fragile under change. File → Options → Data Load → untick Auto date/time, and use a single marked date table.
What is detected
Auto date/time creates one hidden calendar table per date column (n detected). They inflate model size and refresh time and hide the real date table from users.
Why it matters
Wrong in some filter contexts, slow, or fragile under change. Fix in the next iteration.
How to fix it
File → Options → Data Load → untick Auto date/time, and use a single marked date table.
