Future Dated Data in Salesforce
As noted in the Metric Builder, by default Ambition defers processing future-dated data.
This is by design to prevent issues with systems that create tasks/events years out into the future.
If your Ambition Metric values are lower than they should be and your source-of-truth values contain records with future-dated data this is most likely the problem.
The good news is that we can change an internal setting for you to rectify the issue, reach out to firstname.lastname@example.org for help!
