On your homepage, click on the integration link. There is an icon to download the demographic exception report, click to download the excel file. There is a student on that report with a duplicate District ID. 

To correct students with Duplicate District ID, follow these steps:

Navigate to the Searches page in SEIS. In the Criteria section add district ID and enter the district ID. Delete the "Exited Students" criteria then press search. 

Two students records will appear. Edit the record and remove the district ID from the student record that is no longer active. The new file will update the active students.
