Plant to Plant Transfers – Field plant to field plant
Why carry out plant to plant transfers:
Materials are transferred between fields plants for various reasons, for example one plant may be the focal point for purchase and distribution of certain materials to other fields plants, there may be an urgent requirement for materials in one plant which are in stock in another, or materials which are surplus to requirements in one plant may be redeployed to another which has demand for them.
