Buyer, multi-supplier, multi-stage supply chain management system with lot tracking

A global supply chain management system in an environment of multiple suppliers forming supply chains for one or more buyers connected over the Internet. The system includes a global processor with logic that maps "local" supply information for each buyer and each supplier, represented in one or more property tables having master information correlated to local information for each buyer and each supplier. The system manages processes from an input of lots to an output through supplier stages where clients each use fragmented different local information. A correlation means uses base lot indicators, one for each of the lots in common for all of said stages and executes supply chain management functions for tracking lots through the supplier stages.
