The information about the materials that a company procures or produces, stores, and sells.

The parts master is the company's central source for retrieving parts-specific data. This information is stored in individual parts master records.
Vehicle Sales and Service uses the VSS-specific parts master transactions /DBE/MM01, /DBE/MM02, and /DBE/MM03. These VSS parts master transactions provide the same functionality as the standard MM transactions. The only differences are:

The user interface is optimized for automotive dealer businesses. Fields relevant for purchase, inventory, and accounting are grouped within one screen for each area.
Indicators for specific automotive dealer business requirements:
- Return Part

Identifies the part as one that must be returned to the OEM (required for warranty claim processing).

- Retention Obligation

Indicates that the part should be retained, according to OEM guidelines. Usually, you keep the part in a separate bin, in the event that the OEM requests the part.

- Check Multiple Entry

If you set this indicator, the system checks whether the part is already used in the order.

- Subject to Disposal

Indicates that this material should be disposed.

You can assign a used part to an exchange part, indicating that this part is relevant for the exchange process. For more information, see Exchange Parts.

Integration

The parts master is used by all components in the VSS and SAP Logistics System. The integration of all parts data in a single database object eliminates redundant data storage. In the SAP Logistics System, the data contained in the parts master is required, for example, for the following functions:

In Purchasing for replenishment
In Inventory Management for goods movement postings and physical inventory
In Invoice Verification for posting invoices
In Sales and Distribution for VSS part sales processing
In Production Planning and Control for parts requirements planning, scheduling, and work scheduling

In Customizing for Logistics – General under Material Master > Configuring the Material Master, you can configure the master to suit your specific requirements.
For more information about the material master, see Material Master (LO-MD-MM).
