Future Dated Data
As noted in the Metric Builder, by default Ambition defers processing future-dated data.
Ambition processes data into metric values when the Date Field contains a date of Today + 1 day.
Deferred processing is by design to prevent issues with systems that create tasks/events years out into the future.
If Metric values are lower in Ambition than your internal reporting and your source-of-truth values contain records with future-dated data, deferred processing is most likely causing the disconnect.
Deferred processing is an internal setting that can be altered to rectify the issue. Reach out to firstname.lastname@example.org to find out more.
