This error occurs because when the ELAS Start Date is populated, the date must be on or before the Student Information (SINF) file Effective Date.
Do not address ANY CERT errors until after the enrollment updates (SENR, SINF, SELA and SPRG) 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:
Verify the data in the student's Language Assessment (LAC) record. If necessary, use the SELA Import Process to update the ELAS Start Date and ELAS Code fields. If the effective dates are incorrect in the Student Information (SINF) file, update the dates in the CALPADS Log Details (LGD) table.
