Hi Adhi,

MDG is integrated into the SAP system landscape. MDM is based upon a diffrent technology.

MDG offers Central Data Maintenance using the SAP standard workflow out of the box. It uses the same underlying database structure, functions, process of core SAP where as this is part of the standard delivery.

MDG is add on component of SAP and it can share the same SAP ERP server. You can deploy MDG upon existing ERP systems or place a standalone MDG Hub in you system landscape.

 

MDG offers a single User Interface that can be shown either in SAP Portal or NetWeaver Business Client. It combines all the actions starting from workflow, data maintenance, data distribution, and so on in a single UI. There are no client specific tools needed.

As MDG is integrated with SAP it can send or receive data from any source, SAP Systems like ERP, SRM, CRM, where as MDM needs a third party middleware system for interfacing the MDM to any other systems.

thnak you,

Parvez

Hi Adhi

In most businesses benefits can be acquired in the area of master data. An efficient master data maintenance, which is implemented across systems and applications, avoids conflicts and reduces costs.


For an area-wide generation of consistent master data, which is comprehensive and valid along the supply chains, SAP provides the Master Data Management (MDM) and Master Data Governance (MDG) tools.

Initially the approach of Master Data Management (MDM) and Master Data Governance (MDG) is similar.


The master data of individual systems are consolidated with the SAP Business Objects Data Services and a keymapping is established. In the latter the master data and the respective source system are listed in a table. Same master data from different systems is provided with a global ID in order to combine them.

The difference between Master Data Management (MDM) and Master Data Governance (MDG) lies in the distribution of data.


Master Data Management (MDM): In the MDM solution the master data is directly distributed to the ERP systems via the Process Integration (PI). Master data changes are purely undertaken from the MDM and updated in the ERP system from there.


Master Data Governance (MDG): In the MDG data circulates in a circuit. The data comes from the ERP system and is adjusted and consolidated with the MDG. The addition and change of data takes place purely here and is still distributed via the Process Integration (PI).


Which of those solutions is better suited for individual business applications depends on technical and process oriented criteria.


MDM uses own flexible data models and is basically usable for all master data objects, whether or not they are coming from SAP system environments.
MDG allows a centralized master data management within the SAP Business Suite and uses ERP data models (prerequisite is the application of ERP 6.0 and the enhancement package 5). Those master data management tools are preferable when SAP uses ERP as master data server and proprietary development is integrated.
