Resolve issue where the IMb User Interface reports show a letter or flat mail piece having been scanned by USPS before it has been mailed in MAIL360 Data Manager

Issue

User Interface reports show a letter or flat mail piece having been scanned by USPS before it has been mailed.

Cause

MAIL360 Data Manager's (DM) tracking reporting is all based *only* on scan data received from the USPS.  

When a Full Service IMb mailpiece goes through one of the USPS's scan machines, a scan event is sent to Pitney Bowes Software and is then forwarded to the user's DM machine.
The scan event data contains information such as the IMb of the mail piece, the date/time of the scan, what USPS facility the scan was being done at, and a 'USPS Operation Code' about what type of scan it is.

When a DM report says that a mail piece has been scanned, that is because DM has received scan data from the USPS that a mailpiece was scanned with that IMb.  
If the mail piece has not been mailed yet, then there must have been another mailpiece with the same IMb that received a scan. 

NOTE: For purposes of tracking a mail piece, the USPS, and therefore DM, only uses the first 20 bytes of the IMb. Those 20-bytes include the Barcode ID, Service Type ID (STID), Mailer ID, and the Serial Number.  
It does *not* include the 'Routing Code', which is the ZIP/ZIP+4/Delivery Point Code.  Therefore even if a mailpiece with the same first 20-bytes is going to a different address, it will be seen as the same mailpiece by the USPS and DM.

Resolution

UPDATED: August 4, 2017
Per the USPS, an IMb must not be used on a mailpiece again for at least 45 days.  That is the period the USPS has allowed for them to insure that pieces with the same IMb will not still be in their system.

The resolution is that the mailer must have processes in place to ensure that the same IMb (the first 20-bytes, up thru the serial number) is not used again for at least 45 days.
