Friday night I stayed to watch the unattended DataCare run. The errors showed up when the data being checked was IC Item Data. The records being checked showed 1-PO-nnnnnn. My purchase order number format. I don't know if the 1- record is header or detail record. DataCare didn't make any attempt to fix the errors. I haven't had to restore any files in the past year or so. It is still showing 6 errors with no additional information in the verbose listing or IRINTERR.*.
