Explanation For Creating Material Master Record

What is MMR (Material Master Record)?

MMR is a data record containing all the basic information required to manage a material.

It's a master record maintained in the system that contains all the specific data relevant to a material.

Number Assignment:

MMR can have either internal or external number range assigned as per the configuration done at the time of implementation.

Material type:

Materials which have similar characteristics are grouped under the same material type.

Material type controls

1. Number range

2. Screen sequence

3. User departments/ views

4. Type of procurement

5. Internal or external number assignment

Material valuation:

- Standard price procedure - price control is "S"
