If you rolled over Grading, and your Grade Plan Formulas were not included, the most likely reason is that Marking Periods were not created for the next school year. If Marking Periods are not created for the next school year before performing the rollover, the formulas will not have the correct information to reference, and will not be created.

Rollovers cannot be re-done, so in cases such as this, Formulas will need to be manually added to Grade Plans
