Physical Inventory Tag count in JDE

Hi

We intend to use Physical Inventory Tag count (JDE WS A 7.3 cume 12). Please advise on following

• If there are multiple tags for an item in a single location in branch, will JDE cumulate the quantity from all the tags for calculating on hand for the same item location(in a branch) on update tag count. Or will it update the onhand balance based on the last tag for the same item location.
• As per oracle document id 626812.1 P41602 (tag count entry ) has following processing option - Enter a '1' to allow multiple tags for an Item/Branch/Location/Lot. We do not see it in our instance even though we are on WS A 7.3 cume 12.
