How to Change a Material Master with MM02 in SAP S/4HANA

Open the material change transaction

Open SAP Easy Access and enter the transaction code MM02 in the command field, then press Enter. This is the standard transaction code for changing a material master record.

Enter or find the material number

On the Change Material (Initial Screen), enter the material number in the Material field — for example, 2263. If you don't know the material number, use the F4 help (search function) to display a list of available materials and their descriptions, then select the correct one.

Select the required views

After entering the material number, click Enter or Continue. In the view selection screen, choose the following views:

• Basic Data 1
• Purchasing
• Accounting 1

Update weight and dimension data

In the Basic Data 1 view, go to the Dimensions/EANs section and enter:

• Gross Weight: 40
• Net Weight: 30
• Unit of Weight: KG

Set the purchasing value key

Switch to the Purchasing view and locate the Purchasing value key field in the Purchasing values section. Click the selection button next to the field to open a popup showing the available purchasing value keys and their parameters, such as reminder deadlines, tolerances, and procedures.

Select Value Key 1 from the list, then confirm your selection to populate the field. This key determines how purchasing conditions — tolerances, delivery deadlines, and price deviations — are managed for the material, and it also sets reminder parameters for late deliveries or payments.

Update the standard price and valuation class

Switch to the Accounting 1 view. In the Prices and Values section, update the Standard Price field to 499.00 EUR. The standard price is a fixed value used for stock valuation and remains constant unless changed manually.

In the same view, under General Valuation Data, set the Valuation Class field to 3100 for Trading Goods. The valuation class determines how the material is valued in terms of costs and which accounts are used for postings.

Save your changes

Once you have verified all updated fields — gross weight, net weight, purchasing value key, standard price, and valuation class — click the Save button at the bottom right of the screen to apply your changes.

Confirm the update

After saving, check the confirmation message at the bottom left of the screen. It should read Material 2263 changed, confirming that your changes have been successfully saved in the system.
