A stock transfer from plant to plant generally takes place within a company code. It can, however, also take place between two company codes, if the plants are assigned to different valuation areas, which belong to different company codes. Unlike a stock transfer from storage location to storage location, a stock transfer from plant to plant affects both accounting and Materials Planning, as follows: Accounting: Accounting is affected if both plants are assigned to different valuation areas. This means that a stock transfer leads not only to a quantity update but also to a value update (stock value, G/L accounts). Thus, parallel to the material document for stock transfer, an accounting document is created. Materials Planning: Materials planning are affected because a change of plant stock is taken into account by Materials Planning Q.
