It is a key that assigns the material to a material type such as Raw materials, trading goods. This allows you to manage different materials in a uniform manner in accordance with your company's requirements.

  3. From which number range interval the material number comes
  4. Which screens are displayed
  5. The order in which screens are displayed
  6. Which department-specific data is displayed for the user to enter

  8. Price control is done in material type configuration. It can be either
  9. Standard price (S)
  10. Moving average price (V)
