What are Web services?


11/90


Web Serv ic es and SAP BI Why Should You Care?

Simply put, Web services enable SAP BI to expand itsfootprint and impact on your organization

Areas where benefits occur:

1. Extending use of SAP BIs integrated data beyond traditional users

Leveraging existing developments and your data

Integrating your data warehouse into your application infrastructure

Increasing the value of your data warehouse deployments

2. Provision of SAP BI features to other components and applications

Facilitating easier access to data

Enriching the developers toolkit

Providing flexibility to developers

Summary

Opt ions for Consuming BI Dat a w i t h Web Serv ic es

There are 2 primary web services for consuming BI Data:

1. XML for Analysis (XMLA)

2. XML Query Result Set (query_view_data)

Within BI, you can use web services to load BI data or consumeBI Data. In this discussion, we are going to discuss consuming

BI Data.


17/90


XMLA Mot iva t ion

XML for Analysis (XMLA)

Connection to third-party, front-end tools

Development of customer-specific front-end tool, which passes XML-

packaged Multi-Dimensional eXpressions (MDX) statements on to

SAP BI and requests XML-formatted results

Data interchange with other subsidiaries/companies/dashboards/etc.

Implementation

An ICF service is delivered pre-configured

1:n Web Service to query ratio

One service for all queries!

MDX necessary for query processing for navigation step

Web service uses existing SAP BI authorizations of specified user

XMLA Business Sc enar ios

Beyond E-commerce, there is an even greater need to share information.

Add value to your offering by providing self-service access.

An electric utility

company

exposes its BI platform, socommercial and industrialcustomers can betterunderstand their powerconsumption and relatedcosts.

A financial services

company

provides BI Web services, soauditors and regulators havean appropriate level ofvisibility into the company's

dealings.

A brokerage firmsupports BI Web services so

institutional investors cananalyze (in amultidimensional way) theperformance of financialinstruments executedthrough the brokerage.

Just-in-Time Inventory Consumer provides to a Supplier just-in-time

inventory data reports exposed as Webservices.

Metrics represented in the reports alert aboutlow inventory.

The reports are interactive, so you drill into

historic data, comparing today's fluctuation instock levels with corresponding days in otherweeks or months.

Market/Environment data Nielsen and others offer their services in the

yellow pages.

Integration and consumption of such databecomes much easier without requiring a veryclose business relationship with such serviceproviders.

XML Query Resu l t Set - Mot iva t ion

XML query result set Simple access to query results as XML list output

Development of customer-specific, front-end application reading SAP BI data

Data interchange with other subsidiaries/companies/dashboards/etc.

Implementation

An ICF service must be created

1:n Web Service to query ratio

One service for all queries!

No additional MDX necessary (only XMLA requires this), therefore no slicing-and-dicing navigation directly possible without Web API

Simple input parameters: InfoProvider, Query or Query View, filters, setting anavigation status, etc.

Support for WEB API commands available. Variables, Variants, or Filter Valueswould be specified via WEB API commands.

Web Service uses existing SAP BI authorizations of specified user

BAPI s?

Common BAPIs you may want to use:

1. BAPI to write to transactional cube2. BAPI to read and write BI documents on master data and

transactional data

3. BAPI to pull a report list

You can create BAPIs to interact with your BI System.
