The plant parameters are a summary of the plant-dependent control parameters of inventory management and physical inventory. In Customizing, you can find the settings under Materials Management→Inventory Management and Physical Inventory→Plant Parameters.
Be aware that most of the inventory management functions are configured not only depending on the plant. Often there are other settings that need to be made depending on the movement type or other values. You should therefore make the settings for a specific function in the corresponding Customizing activity. This ensures that you do not forget any relevant settings.
