Warning(s)
|
A value or values in a record does not match an EIM valid value or values.
To view error details, click the "View Processed Records" button to bring up the dataset, and then click the "Warnings" link under "Submittal Status." Alternatively, you can click the "View Error Records" button to see all the error details at once.
Although we would like these errors fixed, Warnings will not prevent the data submittal process from being considered complete.
If you think a value with a Warning should be added to EIM, please contact your Data Coordinator.
