Stock transfers can occur between different stock types, materials, storage locations, and plants. The document describes various scenarios for transferring stock, including checking the material document, accounting documents, and stock overview after each transfer. Transfers can be done simultaneously between plants or by issuing from one plant and receiving at another. When using the MM interface, material must be maintained at the issuing plant with sales information and a customer created for the receiving plant, then a PO is made at the receiving plant.
