In the SAP MM module, material master data refers to all the material master records that are stored in the system. In other words, material master data consists of the description of all the materials that an organization not only purchases but also produces and keeps in its stock. The material master data acts as a central database of information for the materials in an organization.
Maintaining the details of all the materials at a central location not only minimizes the risk of data redundancy but also allows other departments of the organization to share this data among themselves. The other departments of the organization can use the material master data to perform various tasks, such as invoice verification and inventory management. The material master record is used by different departments of an organization, and each department requires different information about the material. For example, the purchasing department might require only the price of the material to perform price control functions; whereas, the sales department might require the sales data to prepare the sales graph of a given period of time.
To facilitate locating the relevant data, various fields have been provided in the Create Material (Initial Screen). Every department can easily locate and access the data required by it by entering the relevant details in these fields.
While creating the material master record, the first screen that appears is the Create Material (Initial Screen), as shown:
Note: You can use the MM01 transaction code to access the Create Material (Initial Screen) screen.
The Create Material (Initial Screen) allows you to specify various attributes, such as material number, industry sector, and material type, to locate the required data. Let’s explore each of these attributes next.
- The Material Number
A material number is used to uniquely identify a material in the SAP system. It is a unique 18 character field, which is assigned to each material in either of the following two ways:
Refers to the number that the mySAP ERP system assigns to a material while creating its master record
Refers to the number that is assigned to a material by the person who creates its master record
Note: With the SAP R/3 system, you can define one external and one internal number range for each material type or even a group of materials.
- The Industry Sector
Depending upon the industrial use of a material, you need to assign an industry sector to it. The different predefined industry sectors included in the SAP R/3 system are:
- Aerospace and defence
- Chemical industry
- Food and related products
- Mechanical engineering
- Plant engineering and construction
- Service provider
- Agriculture, mining, and manufacturing
You can also create a new industry sector apart from these predefined sectors.
- The Material Type
The materials having common features are grouped together and assigned a material type. For example, in the mySAP ERP system, all the raw materials are grouped together under the ROH group, finished products are grouped under FERT, and semi-finished products are grouped under HALB.Assigning a material type to a material while creating the material master record helps in:
- Assigning a material number
- Assigning the material number range
- Controlling the price of the materials
- Determining the account in which the entry of the material is to be made
- Updating the plants with the value and quantity of the material
- Determining the sequence of screens that should appear after the Create Material (Initial Screen)
of configuration required while creating a new maal type.
Next table lists different material types used while creating the material master data:
|Material Type||Description||Transaction Code|
|Refers to the services that are procured from external sources and cannot be stored, such as legal services or garbage collection.||MMS1|
|Refers to the products created by the organization. It does not contain any purchasing information as the products are not purchased.||MMF1|
|Refers to the products that are procured from external sources and then assembled or processed internally and sold as finished products.||MMB1|
|Refers to the materials that are purchased from the vendors and then sold, without any internal operation being performed on the material.||MMH1|
|Refers to the materials that are used in the production process, such as lubricants or compressed air. It contains only the purchasing information and not the sales information.||MMI1|
|Refers to a set of logical elements that are used to assemble technical objects into clearly defined units. For example, a car is a technical object and the parts of a car, such as the engine and axles, are maintenance assemblies.||MMP1|
|Refers to the material type that is used for all variant configuration materials. A vari ant configuration material is a material that has variables, such as the length of a chain or a belt.||MMK1|
|Refers to the material that is used for packing purposes and can be returned to the manufacturer, such as a crate or drum.||MML1|
|Refers to the reusable packaging material that is used to pack finished goods. The customer is obliged to return the packaging material to the vendor.||MMG1|
|Refers to the consumable material that is not held in stock and not recorded in the inventory.||MMN1|
|Refers to the material that is used to produce finished goods. If the raw material is sold, no sales data is maintained for the same.||MMR1|
|Refers to the material that is managed on quantity basis and not by value.||MMU1|
|Refers to the packaging material that is offered free of charge to the customer in the delivery process.||MMV1|
|Refers to the product that is used by the sales department to monitor the products of the competitor.||MMW1|
After discussing the material types present in the mySAP ERP system, let’s learn to configure, change, and define the number range of a material type.
Configuring the Material Type
To assign a material type to a material, you first need to configure the material type.
You can configure the material type by navigating the following menu path:
IMG > Logistics-General > Material Master > Basic Settings > Material Types > Define Attributes of Material Types. In the Change View „Material types“: Overview screen, select a material type, say DIEN, and click the Quantity/value updating link. The Change View „Quantity/value updating“: Overview screen appears, displaying the content of the folder of the DIEN material type, as shown:
In the Change View „Quantity/value updating“ screen you can configure the following four fields of the material type:
- Qty updating – Specifies whether or not the material can be managed on a quantity basis
- Value updating- Specifies whether or not the material can be managed on a value basis
- Pipe. mand.- Specifies whether or not the material is subject to mandatory pipeline handling
- Pipe allowed- Specifies whether or not the material is subject to pipeline handling
Note: The best way to create a new material type is to select and copy an existing material type to the new material type. This method helps in reducing the amount of configuration required while creating a new material type.
Changing the Material Type
At times, you may need to change the material type of a material. For example, a material that was initially being used for in-house production may now need to be sold. In such a situation, its material type needs to be changed from ROH to HAWA.
Let’s change the type of a material – navigate the following menu path in the SAP GUI:
Logistics > Materials Management > Material Master > Material > MMAM – Change Material Type.
Note: You can also use the MMAM transaction code to access the Change Material Type: Initial Screen.
- Enter the number of the material whose material type you want to change in the Material text box.
- Enter the new material type of the material in the New material type text box.
- Enter the old material type of the material in the Old material type text box.
- Click the Save () icon to save the changes.
The mySAP ERP system imposes certain restrictions while changing the material type of a material.
The following are the areas in which restrictions are imposed while changing the material type in the material master record:
- Price – specifies that the new material type can only allow standard price in case the old material type does not have any specific price control.
- PRT view – specifies that if the old material type has a PRT view, it should also be maintained in the new material type.
- Configurability – specifies that if the old material type is not configurable, the new material type is also not configurable.
- Inspection plan – specifies that inspection plans, if allowed in the old material type, should also be implemented in the new material type.
- Process indicator specifies that if the old material type is being used as a process indicator, the new material type should also be used as a process indicator.
- Manufacturer part indicator – specifies that if the old material type is being used as a manufacturer part indicator, the new material type should also be used as a manufacturer part indicator.
Now, let’s learn to define a number range for the material type.
Defining a Number Range for the Material Type
After configuring the material type of a material, you need to define a number range for the material type. The following are the ways to define a number range:
- Internal number assignment – refers to the number that is assigned by the system within a number range interval.
- External number assignment – refers to the number that is assigned by the user within a number range interval
Let’s now learn to create the material master record
Creating a Material Master Record
The material master record comprises all the information that the company needs to manage a material. The data stored in the material master record is descriptive in nature, as it contains information, such as the name, size, or dimension of the material. The material master record also contains data that the system uses to perform various control functions on a material, such as MRP type and price control.
The following are the three ways to create a material master record:
- The immediate process
- The scheduling process
- The special process
Let’s now discuss each of these in detail.
The Immediate Process
The immediate process helps you to create the material master record immediately. In this process, you just need to enter the basic information about the material to create its master record.
Let’s create the material master record.
Navigate the following menu path in the SAP GUI: Logistics > Materials Management > Material Master > Material > Create (General) > MM01 – Immediately.
Note: You can also use the MM01 transaction code to access the Create Material (Initial Screen).
The Create Material (Initial Screen) contains the following fields:
- Material – allows you to enter the material number;
- Industry sector – allows you to enter the industry in which the material will be used;
- Material Type – allows you to enter the type of material;
- Change Number – allows you to enter the number if the customer is using Engineering Change Management. This is is an optional field;
- Copy from Material – allows you to enter the material number of a material, which provides information about the new material. This is an optional field.
Enter the required information in the Material, Industry sector, and Material Type text boxes and press the ENTER key.
In the Select View(s) dilaog box, you can describe the screens that you require to enter detailed information about a material.
Select the Basic Data 1 option from the View list box of the Select View(s) dialog box and press the ENTER key.
The Create Material screen appears
Enter the required information about the new material in the relevant fields.
Click the Enter () icon.
Click the Save () icon to save the changes.
The Scheduling Process
In the mySAP ERP system, instead of creating the material master record immediately, you can schedule it to be created at a later date. This is known as the scheduling process, where you can enter the information about the material for which you want to create the material master record and specify the date on which you want the material to be created in the records. The data of the new material is saved and created in the records on the specified date.
Let’s create the material master record using the scheduling process.
Navigate the following menu path in the SAP GUI:
Logistics > Materials Management > Material Master > Material > Create (General) > MM11
Note: You can also use the MM11 transaction code to access the Schedule Creation of Material (Initial Screen).
- Enter the material number in the Material text box.
- Enter the industry in which the material will be used in the Industry sector text box.
- Enter the type of material in the Material Type text box.
- Enter the date on which the material is scheduled to be created in the Chge sched. for text box.
- Enter a number to identify the change master record in the Change Number text box.
This is an optional field.
Note: A change master record consists of data such as the reason for changing the material master record and the administrative data of the material master record.
- Enter the material number of a material, which provides information about the new material in the Copy from Material text box. This is an optional field.
- Enter the required information in the Material, Industry sector, Material Type, and Chge sched. for text boxes and press the ENTER key.
The Select View(s) dialog box opens:
Select the Basic Data 1 option from the View list box of the Select View(s) dialog box and press the ENTER key.
The Schedule Creation of Material screen appears, as shown:
Enter the required information about the new material in the relevant fields and click the Save () icon to save the changes and create the material master record.
The Special Process
In the discussion above about the immediate and scheduling processes, you learned to create records for general materials. In other words, in both these processes, you need to specify the type of material in the intial screen. The special process of creating the material master record is used in situations where the type of the material has already been decided. In such cases, you need not mention the material type.
Let’s create the material master record by using the special process.
Navigate the following menu path in the SAP GUI:
Logistics > Materials Management > Material Master > Material > Create (Special).
A list of material types appears:
Select the type of material whose record you want to create from this list. In this case, we have selected the MMR1 – Raw Material option.
The Create Raw Material (Initial Screen) appears:
Note: Refer to table above for the list containing all the transaction codes to create different material types using the special process.
Enter the required information in the Material and Industry sector text boxes and press the ENTER key.
The Select View(s) dialog box opens, select the Basic Data 1 option from the View list box of the Select View(s) dialog box and press the ENTER key.
The Create Raw Material screen appears – enter the required information about the new material in the relevant fields and click the Save () icon to save the changes and create the material master record.
Let’s now explore the various tabs contained in the Create Material screen.
Exploring the Data in a Material Master Record
You have already learned that while creating the material master record for a material, you need to enter various types of information in the Create Material screen, such as the material description, the base unit of measure of the material, and the material group.

Let’s now learn how to modify the material master record.
Changing the Material Master Record
You can change the material master record after it has been created and saved in the SAP database. The following are two ways to change the material master record:
- Immediately – changes the material master record immediately
- Schedule – allows you to set a date on which the material master record should be changed.
Let’s change the material master record.
Navigate the following menu path in the SAP GUI:
Logistics > Materials Management > Material Master > Material > Change > MM02 – Immediately
Note: You can also use the MM02 transaction code to access the Change Material (Initial Screen).
Enter the number of the material that you want to change in the Material text box and press the ENTER key.
Then select the Basic Data 1 option in the Select View(s) dialog box and click the Continue () icon.
The Change Material 1screen appears.
Enter the new record in the respective text boxes and click the Save () icon to save the changes.
You can schedule a time to change the material master record either by using the MM12 transaction code or by navigating through the following menu path:
Logistics > Materials Management > Material Master > Material > Change > Schedule
In the Schedule Changing of Material (Initial Screen), you need to enter the following information:
- Material – refers to the material number
- Chge sched. for – refers to the date on which the change is scheduled
Deleting the Material Master Record
You can also delete the master record of a material that is no longer required. Let’s delete the material master record.
Navigate the following menu path in the SAP GUI:
Logistics > Materials Management > Material Master > Material > Flag for Deletion > MM06-Immediately
Note: You can also use the MM06 transaction code to access the Flag Material for Deletion: Initial Screen.
Enter the material number in the Material text box and press the ENTER key nad the Flag Material for Deletion: Data Screen appears.
Select the Material check box in the Flag Material for Deletion: Data Screen to delete the material at the client level and the lower levels and press the F11 key to flag the material for deletion.
A system message indicating that the record has been flagged for deletion appears in the system message line of the screen.
Defining Field Selections
The field selection group of a material helps you to identify whether or not entering a value in a particular field is mandatory or optional. You can define the field selection group in the Change View „Field Groups“: Overview screen. You can access the Change View „Field Groups“: Overview screen, by using the OMSR transaction code:
In the View „Field Groups“: Overview screen, double-click any transaction to modify/display the values of its field. When you double-click any transaction, the View „Field Groups“: Details screen opens:
While defining the field selection for the material master record, you should remember the following points:
- You should not change the field status of the field selection group that has the field reference key with the SAP prefix
- A new field reference key should begin with Y or Z.
- You cannot change the field reference key for transaction codes and procurement types that are already configured.
- The new field selection groups should be taken from those groups that are not already configured.
Creating Material Groups
– You can create different material groups to distinguish various materials. For example, a computer manufacturing organization can classify a computer as a desktop, laptop, or a server, and each classification would have its own individual group.
You can create a material group by accessing the following menu path:
IMG > Logistics – General > Material Master > Settings for Key Fields > Define Material Groups. Pictute below shows the preceding menu path:
The View „Material Groups“: Overview screen appears.
In the View „Material Groups“: Overview screen, you can group together the materials or services having common attributes.
