When reading overlay validation reports, be sure to check the summary and the details sheets. The summary will show the validation and number of times it was seen. The details sheet will give specific lines and further details for each validation error found.
Below is a list of issues that can occur during an overlay. An Error means that none of the rows could be loaded. A Warning means DISCO performed the overlay, but the documents may need to be checked for completeness.
DISCO attempts to include all identifiable validation issues in each Validation report, but some validation checks cannot be run if there are issues in earlier validations.
