Occasionally breeding details are overlooked before the end of the breeding season.
If details of a positive pregnancy scans on a mare from the previous breeding season are missing, and you know the Due Date to be in the current season, you will need to run the Final Scan Positive - Last Season procedure.
This updates the mare status, applying a Final Scan Positive result, and in doing so will apply a Due Date, so that foaling can be completed in the current season.
