various application scenarios.<br />
1. For shipment and receipt verification, applications will request the number of<br />
Logistic Units such as Pallets and Cases moving through a portal, totaled by Pallet<br />
and Case GTIN across all serial numbers. Object types other than Pallet and Case<br />

2. For retail OOS management, applications will request one of 2 things:<br />
a. <strong>The</strong> number of Items that were added to or removed from the shelf since the<br />
