Abstract
The present invention provides a system and method for creating an exclusive ID to a split lot in a multiple-plant enterprise. When a lot is divided, the split lot is first assigned a main code by a main ID unit. When the split lot is divided in the initial plant, a split ID unit assigns a split code to the split lot according to a sequence. When the split lot is not divided in the initial plant, the split ID unit assigns a plant code and a split code according to a sequence to the split lot. All of the codes of the lot are stored in an ID storage unit for lot administration.
