Fabric IQ

Hello jcotton,

From your description, this doesn't sound like expected behavior.

The key observation is that the override reports "Value saved", but the displayed value doesn't change until a bulk edit (for example, +100 followed by -100) is performed on the Base sheet. That suggests the input column may not be fully initialized or recalculated immediately after the scenario is created.

Since the bulk edit doesn't introduce a lasting data change but does cause subsequent scenario overrides to work correctly, it appears to be triggering a refresh or initialization of the underlying model rather than correcting the data itself.

I couldn't find Microsoft documentation describing this as a known behavior or limitation of Fabric IQ. Based on your reproduction steps, I would recommend:

Verify whether the issue occurs with multiple models or only this specific workbook.

Test with a newly created model containing a simple input column that has a default derived from another measure to determine whether the behavior is reproducible.

If the issue is consistently reproducible, open a Microsoft Support ticket or submit feedback, including the exact reproduction steps (new scenario → override → "Value saved" with no visible change → bulk edit → override works). That will help determine whether this is a product defect.

One additional question that may help narrow this down:

Does the issue occur only when the default value is derived from another measure, or does it also happen for input columns with a fixed default value?

That distinction could help identify whether the problem is related to dependency evaluation or to scenario initialization.
