This error occurs because an error-free complete SENR file has still not been posted to CALPADS or students are being skipped in the file that shouldn't be.
Do not address ANY CERT errors until after the enrollment updates (SENR, SINF, SELA and SPRG) and Fall 2 submission (SDEM, SASS, CRSE and SCSE) files have been posted with few to no errors. Most CERT errors are caused by file extracts that have not yet been posted error-free or from data that has not been correctly populated in Aeries.
Resolution:
Post an error-free, complete SENR file to CALPADS. Confirm that all Primary, Secondary, and Short Term Enrollments are being reported.
