Report is Currenty being Edited by SAP_SYSTEM

We receive credit card imports daily at 14:00. If a user has his report open while the import is trying to auto assign his report, I think the report becomes locked by SAP saying: "expense report is currently being edited by SAP_SYSTEM"

Am I correct in my thinking? Also, the import is complete and his report is still locked by SAP. Why?

Thanks for any guidance.
