# MASTER DATA : Master Data is a data that is stored centrally on the server. It contains all the information regarding a material. This information includes the material type, vendor,                 store location, stock , etc.

# MATERIAL MASTER RECORD ATTRIBUTES :
When SAP R/3 MM System is installed  it will include the full set of master records. These Master Records are in the form of entity types that can be copied and filled with specific data.We may wish to edit the format of some of the data fields and perhaps their name or titles, which will appear on the graphical display of the user.And ,of course, we will need to enter the specific details of the material needed inn our company. The system is delivered with the tools to help us make all the adjustments necessary to have our   implementation correctly running our business as soon as possible. For the sake of convenience, the data fields are grouped into clusters called "attributes".

A typical material master record will have attributes as follows:

• General data such as material number, description, units of measure, and technical data.
• Plant-specific data such as material requirements planning type, planned delivery time, purchasing group and batch indicator.
• Evaluation data such as evaluation price evaluation procedure and evaluation quantity.
• Warehouse Management data such as unit of measure, palletization instructions and directions to place in or remove from stock.
• Sales-specific data such as delivering plant and sales text.

Any of these data clusters can be further sub-divided. For example- the plant-specific data might be extended to include the following type of data:

• Storage location such as the permitted period of storage, the individual stock field, or storage area within a storage location where materials are kept.
• Forecast data for this material.
• Consumption data for this material.
