Recommendation for MDM API or Web Services

[Former Member]

Hi All,

Happy New Year.

Any body has the knowledge on MDM ABAP API and WebServices. Can you please provide me the recommendation for each and Performance Analysis for both.

Thanks in Advance,

Best Regards,

Hi,

Web services :-Web services represent a self-contained subset of application functionality allowing different applications from different sources to communicate with each other without time-consuming custom coding. Because all communication is in XML, Web services are not tied to any one operating system or programming language.

Web services for MDM are open interfaces to the MDM Server. They are based on the Simple Object Access Protocol (SOAP) and Web Services Description Language (WSDL) standards. They provide data management capabilities (create, read, update) and access to central key mapping (create, read). MDM Web Services provide synchronous access to MDM for the consumer of the Web services.

The MDM Web services can be used to:

● Manage Master Data Objects

○ Existence check of a central master object before local creation

○ Retrieve details and create a local replicate

○ Create or update master data objects on MDM

● Manage Unique Identifiers of Master Data Objects

○ Remote system registers local object as replicate of global object

○ Key mapping during message exchange on SAP NetWeaver XI

MDM ABAP API :-The MDM ABAP API provides an interface for accessing SAP MDM 5.5 using ABAP. The interface is easy to configure and convenient to use.

It is optimized for ABAP developers and available using ABAP Objects and function modules (partly remote enabled). In addition to the core services performed on the records (create, retrieve, update, delete, query, etc), metadata (tables, fields, etc.) and administrative functions (such as repository) are delivered.The MDM ABAP API empowers ABAP-based applications to control MDM Servers using most of the functions available in the MDM Console and MDM Data Manager applications.

Features-:The API is provided with:

● Interfaces and methods (ABAP objects)

● Function groups and function modules

The interfaces with the extension SIMPLE have the following advantages:

● Simple and comfortable access

● Generic and object-oriented

● Methods use DDIC structures (no arrays, but tables and fields)

Some function modules are remote enabled (Web services, RFC).

Constraints-The MDM ABAP API has the following constraints:

● Update user: Name cannot be updated

● No real values (float single precision)

● General MDM Server problems on those components: user management, trusted connection, etc.
