These three files are considered temporary. The items.csv file is either overwritten or appended to, depending on your selection during the load. The error and success files are always overwritten during the next load.
Use the Successfully Loaded link to view the itemssuccess.csv file—displayed with Microsoft Excel—that contains all the records successfully added or updated in QAD CSS. In order to maintain an audit trail of the updates, make sure that you save this file in an archive directory.
Use the Failed Records link to view the records that were not loaded in itemserror.csv. The last data column indicates the reason for the failure.
