FACTS SIS Users — Be sure to initiate a new DataRollup import after making the changes to correct errors. You will need to wait for the file to process before the changes are reflected in the reports.
See the information here for how to initiate an import manually.
Jupiter Users — Your data syncs every night, however, you can send an import anytime you have a data change. Setup | Import/Export| Data Rollup | Submit to Data Rollup
