You can use the CGORECONSIGN001 (ON_RECONSIGN) (on page 1) setting to determine whether to merge or move the Bill of Lading (BL) items when you re-consign one BL to another BL with identical commodities.
By default, N4 merges the BL items if you re-consign one BL to another BL with matching commodity.
If you override this setting, N4 moves the BL items from one BL to the other BL with matching commodity.
This setting is applicable only for identified cargo lots. You can use the Identified Lots tab (on page 1) in the Bill of Lading Item form to add or edit identified cargo lots.
