The error file is generated when: * You try uploading a Reconciliation Report, but it isn't successful. * You upload a Reconciliation Report that contains both valid and invalid entries. In this case, the valid entries are processed and uploaded. The invalid entries aren't processed and uploaded. The error file contains information about the error(s) that occurred, such as why the upload wasn't successful or why the entries are not valid. You can find the error file that corresponds to your uploaded Reconciliation Report at **\/download/recon-errors/\**. The error file is a CSV file with the following naming convention: **PartnerReconciliationErrors\_\\_\\_\\_\\_v1.csv** where **\** and **\** are in the format of **yyyymmddThhmmssZ**. The error file has the same date as the corresponding Reconciliation Report you uploaded.
