5-3 Nesting/Sortation (MPE) Verification

5-3.1 Description

It is a requirement for Automated Verifications for the piece IMb identified in eDoc to correctly identify nesting information. More specifically, the Handling Unit the piece is nested in, otherwise known as the piece’s “parent” handling unit, must be the same as the parent handling unit detailed in the eDoc. To verify this, information in the eDoc is compared to a reconstructed Handling Unit, which is logical representation of a tray based on patterns derived from MPE piece scans. A Nesting/Sortation Error is logged if the MPE piece scan is nested in a different parent handling unit than what was identified in the eDoc and the presort level of the MPE piece scan’s reconstructed parent Handling Unit does not match the Presort Level of the associated eDoc piece’s Handling Unit. An error is also logged if the Destination ZIP code of the MPE piece scan’s Reconstructed Handling Unit does not match the Destination ZIP code of the associated eDoc piece’s parent Handling Unit.

Nesting/Sortation Errors are determined using scan data from the MPE, including Facility, MPE Machine ID, and Wide Field of View (WFOV) Sequence Number. Each piece scan receives a unique WFOV Sequence Number which is a counter that represents the order in which the pieces are processed on the MPE. A system representation of every tray is created using data from these scans. Nesting/Sortation (MPE) errors are displayed on the Seamless/Automated Verification tab of the Mailer Scorecard (please note that warnings are not included in the Mailer Scorecard metrics unless the metric name specifically calls out warnings).

The description for Nesting/Sortation (MPE) errors is included in Table 5-3.1.1.
