  8. Select the Ok button to confirm entry.
  9. Close the Ascent/Xpress Setup program.

Resend the manifest files:

Due to the error, the manifest file for the day was not transmitted, so it still needs to be transmitted. To resend a manifest file(s):
  1. Open Processing:
    • Ascent: Start > All Programs > Ascent > Ascent Processing
    • SendSuite Xpress: Start > All Programs > Xpress > Xpress Processing
  2. Go to Reports > Archive Reports.
  3. Select the Source button in the lower right.
  4. Select the carrier (POS, POM, etc.) for which you were processing end of day when the error occurred, and select the OK button.
  5. In the File Filter field, enter *.ssf and press the Enter key on your keyboard.
  6. In the column labeled F6-Status, double-click on the file name to organize it into Ascending order.
    • After organizing the column, you may see blank entries in the status column, which can be ignored. The only entries we are concerned with are the ones that say Sent or Failed.
    • If you see a Sent status as the first option in the Status column, double-click again on the F6-Status column header to reorder the list again.
    • Scroll down until you see the first entry that has Failed in the Status column.
    • If all statuses are Sent, then all of your manifests files have been sent to USPS and no further action is required.
  7. Select the row with the Failed status and select the Send button. This will resend the file to USPS.
  8. Repeat step 6 and 7 for each Failed manifest.
  9. Once all manifest files have been successfully sent, select the Get button at the bottom to get any files from the USPS server that were missed due to the logon issue.
  10. Once that process completes, close the Archived window by selecting the closing door icon and continue your normal shipping processes.
