Many customers regard NetWeaver Business Client (NWBC) as very desirable. Yes, they do appreciate SAPGUI for being pretty robust, reliable, well-hung, and last but not least fast, a good working environment for heavy-duty backend users. --
But NWBC has the Side Panel, which is an awesome tool for enhancing the user experience while being minimally disruptive:
Some other very good reasons to adopt NWBC:
At this point, clients sometimes work with me to help them evaluate, plan, and, if all goes well, implement NetWeaver Business Client in their SAP landscapes. When, invariably, the topic of SSO comes up, those customers who don’t have SAP Single Sign-On 2.0 licensed, make the following discovery:
SAP customers rarely accept it that implementing a new technology or software should make things worse for them (tongue in cheek: Maybe they should know better by now). So a logon screen in a place where there used to be a seamless single sign-on experience is perceived as completely unacceptable, no matter how bad the logon screen per se really is. This is when they declare the issue a potential dealbreaker and start looking for possible solutions.
(For the sake of completeness, I should mention that one of these possible solutions is a rather tactical custom development project solution that has been implemented at a few clients, but I’m not going into that here because I want to comment on SAP’s standard software and not individual custom project solutions.)
The obvious solution is SAP’s own SAP SSO 2.0, which is a comprehensive solution for many different single sign-on requirements and able to provide seamless integration even in complex and heterogeneous scenarios. It allows customers to implement single sign-on solutions for on-premise systems, cloud-based systems, social networks, mobile devices, and so on. It combines the use of wide-spread industry standards such as SAML with SAP’s proprietary technologies and integrates SAP and non-SAP systems alike.
Because it is a separate product, SAP SSO 2.0 comes with a price tag. Just to get some indication: Although the actual quotes SAP gives seem to vary, my sources for pricing information all said that the quotes were in a range where, for a company with 40,000 users, the bill can easily exceed 1,000,000 USD.
In my humble opinion as an enterprise architect, it is a reasonable price tag if you are looking for a strategic solution to address the growing SSO needs in a landscape that is becoming increasingly complex, and in which there is at least the perspective of needing to integrate more and more cloud solutions in the future.
However, when you are planning to test the waters with NetWeaver Business Client and are, for now, happy with your SSO and Identity Management architecture, and all you want is to give NWBC to a pilot department, and you don’t want them to have a logon screen with NWBC where they didn’t have a logon screen with SAPGUI, the price tag is too hefty. In my conversations with SAP customers and other consultants, I have learned that this is an actual problem for the adoption of NWBC.
I believe that SAP SSO 2.0, as a comprehensive solution, provides great value and it’s reasonable that a full-blown implementation should have a price tag that corresponds to the value it creates. It’s well-positioned as a strategic solution.
With NWBC, however, there is a need for a tactical solution that doesn’t address all the issues for which you would get SAP SSO 2.0, but that simply replicates the behavior of the Portal-to-SAPGUI integration with NWBC, so that using NWBC in lieu of SAPGUI doesn’t make things worse.
I can see two possible solutions for this, one that requires SAP to code and one that doesn’t.
1. Coding-based solution: Change the way Transaction iViews in the Portal work slightly.
(I am actually thinking about building a prototype for a similar solution, but it’s early days. I hope SAP will beat me to it.)
2. Coding-free solution: Offer an NWBC-only license model for SSO 2.0
