As per the below info in the help file:
I understand that these status are set by an agent which checks the order release quantity against the shipment source location quantity loaded and shipment dest location quantity delivered.
<LI class=kadov-p-CBullet>
QUANTITY VALIDATION DESTINATION - Same as for SOURCE below, but the location checks will compare the order destination to each ship shipment's destination and look for shipments with a destination location with a SHIP FROM/SHIP TO role. This status is set by the Determine Quantity Validation agent action.
<LI class=kadov-p-CBullet>
QUANTITY VALIDATION SOURCE - These statuses are set by the Determine Quantity Validation agent action.- <LI class=kadov-p-CBullet>MATCH - If ALL of the shipments have a BOL_ACTUALS status of ENTERED_TRANSMISSION and the total shipment ship unit quantity is equal to the order release ship unit quantity, then the order release status QUANTITY VALIDATION SOURCE is set to MATCH.
<LI class=kadov-p-CBullet>NOT STARTED - If NONE of the shipments have a BOL_ACTUALS status of ENTERED_TRANSMISSION the order release status QUANTITY VALIDATION SOURCE should be set to NOT STARTED.
<LI class=kadov-p-CBullet>OVER - If ALL of the shipments have a BOL_ACTUALS status of ENTERED_TRANSMISSION and the (total shipment ship unit quantity + ship unit quantity on the unplanned order movements) > order release ship unit quantity, the order release status QUANTITY VALIDATION SOURCE is set to OVER.
<LI class=kadov-p-CBullet>PARTIALLY LOADED - If only some of the shipments have a BOL_ACTUALS status of ENTERED_TRANSMISSION, the order release status QUANTITY VALIDATION SOURCE is set to PARTIALLY LOADED. - UNDER - If ALL of the shipments have a BOL_ACTUALS status of ENTERED_TRANSMISSION and the (total shipment ship unit quantity + ship unit quantity on the unplanned order movements) < order release ship unit quantity, the order release status QUANTITY VALIDATION SOURCE is set to UNDER.
