Checks

Alice Report offers you different checks to help you building your use case logic.

The check value can be a number or null. All checks range from 0 to 100 with threshold at 50.

• Values greater than or equal to 50 mean that the check has passed.

• Values ​​below 50 mean that the check has failed.

• Null values mean that the check does not apply.
