SAP MDM Interview Question And Answers
What is SAP Master Data Management?
SAP Master Data Management (SAP MDM) enables information integrity across the business network, in a heterogeneous IT landscape. SAP MDM helps to define the business network environment based on generic and industry specific business elements and related attributes – called master data. Master data, for example, cover business partner information, product masters,product structures, or technical asset information. SAP MDM enables the sharing of harmonized master data, formerly trapped in multiple systems, and ensures cross system data consistency regardless of physical system location and vendor. It helps to align master data by providing services that recognize identical master data objects and keep them consistent. In addition, it enables the federation of business processes, by providing consistent distribution mechanisms of master data objects into other systems, within the company and across company boundaries.
What are SAP MDM’S major benefits?
SAP MDM: Helps companies leverage already committed IT investments since it complements and integrates into their existing IT landscape. Reduces overall data maintenance costs by preventing multiple processing in different systems. Accelerates process execution by providing sophisticated data distribution mechanisms to connected applications. Ensures information consistency and accuracy, and therefore reduces error-processing costs that arise from inconsistent master data. Improves corporate decision-making processes in strategic sales and purchasing by providing up-to-date information to all people.
What are the MDM Business Scenarios ?
-Master Data Consolidation
-Master Data Harmonization
-Central Master Data Management
-Rich Product Content Management
-Customer Data Integration
-Global Data Synchronization
What is Master Data Consolidation ?
In Master Data Consolidation scenario, users wield SAP NetWeaver MDM to collect master data from several systems at a central location, detect and clean up duplicate and identical objects, and manage the local object keys for cross-system communication.
What is Master Data Harmonization ?
In Master Data Harmonization scenario enhances the Master Data Consolidation scenario by forwarding the consolidated master data information to all connected, remote systems, thus depositing unified, high-quality data in heterogeneous system landscapes. With this scenario, you can synchronize globally relevant data across your system landscape.
What are all the capabilities and functions of SAP NetWeaver MDM ?
SAP NetWeaver MDM is used to aggregate master data from across the entire system landscape (including SAP and non-SAP systems) into a centralized repository of consolidated information. High information quality is ensured by syndicating harmonized master data that is globally relevant to the subscribed applications. A company’s quality standards are supported by ensuring the central control of master data, including maintenance and storage.

What options are available for resending from MDM within XI or R/3 in case an update fails?
If the failure lies with XI or R/3, the same XML can be reprocessed (no resending is required). If there is a validation or data problem, the records needs to be identified and modified in MDM Data Manager Client and the Syndicator batch will resend them as they were updated since the last syndication.
Is it possible to develop web forms (outside of EP6) that link to standard Java MDM APIs and communicate with the MDM repository?
Yes it is possible as you are not limited to the use of iViews that exist. Your own application-specific iViews can be created. You can also access the server with direct calls to the API from the java environment.
How easy is it to maintain the front-end when the data model changes?
The effort depends on the number of fields required for the front-end. Fields that are added have no impact. Fields that are deleted (and maintained in the front-end), need to be removed. Fields that are renamed need to be updated.
How will MDM fit into Enterprise Services Architecture? Which Web services will be provided and when?
MDM is integral to SAP’s ESA strategy. The initial list of documented Web services with MDM 3.0 were provided with MDM 3.0 information release. These refer to the ability to access master data information in MDM as a service to create records, etc. New web services will be available as per the roadmap. With SAP MDM 5.5 in conjunction with SAP Exchange Infrastructure, one can create web services by exposing MDM functions using MDM JAVA or .NET APIs.
How integrated is SAP NetWeaver MDM 5.5 with SAP NetWeaver and applications?
SAP NetWeaver MDM 5.5 is an integral part of the NetWeaver stack. In the current feature release, enterprise application integration, both SAP and non-SAP, is accomplished through SAPXI. Interoperability with other systems is possible via SAP NetWeaver MDM 5.5’s APIs (including ABAP whose development is currently in process). Tight, native integration is part of the SAP NetWeaver MDM 5.5 roadmap and further pre-built integration points will be rolled out as we progress along the development path. SAP MDM 5.5 SP2 will provide view-only iViews for SAP Enterprise Portal.
