SAP Microsoft Interoperability

November 2010 Previous month Next month

In May this year, TopForce applied as IT partner together with an end-user organization for participating in the Duet Enterprise Ramp-Up. Rationale for both organizations to participate in this Rapid Deployment Program is to gain in an early stadium insights and practical experience on the potential and added value of Duet Enterprise.

Our mutual application was accepted by the RDP Program in June. As one of the first activities, both organizations each sent 2 to 3 employees for Duet Enterprise training. Actually this was a requisite for RDP participation. The 5-days training addressed both the infra/operations aspects of Duet Enterprise in the SAP and Microsoft landscapes [3 days], and the development approach in the SAP and Microsoft development suites [2 days].

After this first introduction to the Duet Enterprise product, we received access to the software bits and accompanying documentation. The last mostly in draft versions, understandable as the product is still in Ramp-Up.

Reasons for participating

The mission of TopForce is to deliver the concept of High Performance Workplace for our customers. In essence this means that we aim for ease of use in the daily workspace of the employees, thereby abstracting the nifty details of the total backbone IT landscape. As our background comes from SAP consultancy, at a lot of our customers SAP is [part of] the business back-end. In our HPW vision, one of the means to achieve a pleasant employee workplace is operating the SAP back-end via a SharePoint based front-end (Unlock the value of SAP business processes within a SharePoint based HPW). We defined a conceptual integration architecture for this SAP-backend / MS-frontend interoperability. The architecture is validated via multiple interoperability technologies and products; e.g. WCF to BAPI WebServices, WCF LOB Adapter, Sitrion. Drawback in all was that we still had to develop a lot of the interoperability plumbing ourselves, most noticeable the support for Single Sign-On. Duet Enterprise now promises to be a good (best?) additional alternative for enabling SAP / MS interoperability.

Our partner shares this same goal, but also has a clear additional target. In the recent history several projects have emerged in which SAP / Microsoft integration might be subject for business and IT architectural decision making, and/or in which SAP / Microsoft integration is concrete realized in some aspects. As the role of both SAP as Microsoft server landscapes is gaining importance at this end-user organization, they have the need for consistent design guidance on when and how to achieve SAP / Microsoft interoperability. Duet Enterprise is participated in this context as an important integration technology to consider.

Project team

Our RDP project team consists of the following roles / persons:

From the end-user organization

  1. Project lead
  2. SAP solution architect
  3. Microsoft solution architect
  4. SAP business analyst
  5. SAP infra/operations
  6. SharePoint infra/operations
  7. SharePoint developer
  8. SAP NetWeaver solution architect / consultant

From TopForce as IT partner

  1. SAP / SharePoint interoperability consultant (my participation in this Ramp-Up)
  2. ABAP developer [only temporarily required]

From the combined SAP / Microsoft RDP support team

  1. SAP NetWeaver consultant [from SAP AG]
  2. SharePoint consultant [from Microsoft Services]
  3. Whenever applicable, supplemented with SAP and Microsoft consultants with varying expertise’s; dependent on nature of discussions and encountered issues

Validation approach and activities

The potential of Duet Enterprise is twofold. On one side it delivers directly usable out-of-the-box functionalities, customizable in some degrees to your situation. Second to that, and this is where it strongly differentiates from the original DUET proposition, it provides a SAP / SharePoint interoperability foundation. Although the first is certainly interesting, our main combined focus for now is evaluating Duet Enterprise for the added value on interoperability plumping aspects. This validation is done by means of a real-life custom-developed application. The following activities are executed by the RDP team:

  • Attend the Duet Enterprise training to get acquainted with the infra and development aspects
  • Install and configure Duet Enterprise in the SAP NetWeaver 7.02 and SharePoint 2010 landscape
  • Derive and define the Software Architecture Design for the selected real-life application
  • Discuss the Software Architecture Design with RDP consultants, from SAP AG and Microsoft Corp.
  • Model, compose and [only] where required custom-develop  the interoperability + integration between SAP backend environment, and SharePoint 2010 based front-end
  • Derive and define the Design Guide for SAP / Microsoft integration decision making at business and IT architecture level

Where do we stand / Results so far

In this near-end phase of the Ramp-Up program, approaching the General Availability of Duet Enterprise, it is not viable to go into product details. This will be addressed later, after the successful conclusion of our Ramp-Up participation.

Results and findings that I can share now are:

  • Getting acquainted with the design and development approach for Duet Enterprise application has an initial steep learning curve. Mind you, this will be less after General Availability when the accompanying documentation will be more complete and mature.
  • Installation and configuration of Duet Enterprise takes its time. This is mainly due the complexity of any typical SAP landscape anno 2010 (aka ECC, NetWeaver, Solution Manager, SLD, ESS and MSS, …), and not so much to direct back to Duet Enterprise specifically. On SharePoint 2010 side the work is much less, although also here it depends on the characteristics (complexities) of the SharePoint farm.
  • This RDP project is an evidence for the added value of a mixed SAP / Microsoft development team (Build Your Interoperability Team as 1 of the Steps HowTo begin with SAP / MS interoperability)
  • It pays out if the SAP and Microsoft solution architects are on a general level familiar with the ‘opposite’ platform stack. E.g. what’s the positioning of SAP PI versus Microsoft BizTalk; what is the concept and support of SAP Enterprise Services;
  • It pays out to have at least one team member aboard that has knowledge and practical experience on the SAP / MS interoperability area; knowledge of both technology stacks, interoperability technologies and approaches.
  • And final remark: SAP / MS interoperability is and remains interesting stuff; from business and IT architectural point of views…
