Material Master Common Questions And Answers

1) What is a serial number?

A serial number is assigned to an item to identify it and to store information about it. A serial number is mostly used to refer to equipment such as motors, drills, or vacuums. In MM, an item of material contains a serial number as well as a material number. This combination helps to uniquely identify an item of material.
 

2) What is a class type? How will you configure a class type?

A class type is the SAP system's top-level unit, which is used to control the SAP system's classes. It performs the following tasks:

  • Defines the class objects
  • Checks if class objects can be used in other classes or not
  • Defines the class maintenance screen
You can configure a class type by using the following menu path: SAP Customizing Implementation Guide -> Cross Application Component -> Classification System -> Classes -> Maintain Object Types and Material Types.
 

3) A material does not have a master record. How can we procure that?

There may be instances when a material does not have a master record. You can perform different functions in different situations to procure the master record. For example:

  • You can create a material master record if there is no material master record for a particular material.
  • You can extend the material master record if the material master record exists for a particular material but the user department does not have the master data.
  • You can also extend the material master record if the material master record exists for a particular material and the user department has the master data but it has been entered in a different organizational level.


4) State the importance of classification data.

Classification data allows you to search for materials on the basis of the characteristic values entered into the classes. This feature is very useful when the customer wants to search for a particular vendor and particular batches.
 

5) What is an ABC indicator?

An ABC indicator is an indicator assigned by the ABC analysis procedure. An ABC indicator provides details of the consumption value of the material involved in the ABC analysis. The ABC analysis is performed by multiplying the current price of the materials by their quantity. The different consumption values are given as follows:

  • A materials—Important parts, high usage/consumption value
  • B materials—Less important parts, medium usage/consumption value
  • C materials—Relatively unimportant parts, low usage/consumption value
