Master data comprises data records that are stored in the database for a long period of time. These data records are stored centrally, and are used and processed on a cross-application basis. This avoids the multiple storage (redundancy) of data.
The business partner master data (supplier), the material master data, and the purchasing info record belong to the most important master data in the procurement process.

When a purchasing document is created, data is transferred by default from existing master records to the purchasing document. This reduces the effort required to enter the data. Data such as quantity unit, material short text, and purchase order text are copied from the material master into the new document. The supplier address and data for payment processing are transferred from the supplier master record. Supplier-specific data for a certain material, such as delivery time and price, can be taken from the purchasing info record.
