This document provides instructions for configuring and activating split valuation in SAP to separately value in-house production stocks and externally procured stocks of materials. It outlines the steps to 1) activate split valuation in the system, 2) create valuation types for in-house and external stocks, 3) assign valuation categories to the types, and 4) create material master records and production/purchase orders to value the stocks separately. The purpose of split valuation is to allow different valuation prices for internally produced versus externally sourced materials.
