This document discusses consignment stock processing. Consignment stock refers to goods owned by a company but stored at a customer's location. The customer is not required to pay for consignment goods until removing them from storage. The document outlines the key transactions for managing consignment stock - consignment fill-up, issue, pick-up, and return - and how each transaction affects inventory levels and billing. It also discusses using a special stock partner to centrally manage consignment stock for multiple customers.
