Oliver Wright Class A Reporting and SAP Standard Cube

Question

Dear All,
has someone experiences with Class-A KPIs Reporting in SAP based on the concept of Oliver Wright?
In his handbook he wrote that this concept reflects the effort and effort and achievement of thousands of client companies who have used our checklist standard to differentiate their business. So its supposed that SAP Standard might also support that concept in general by providing eventually standard cube if this trendy in U.S.
Does SAP support that concept or do you know who is there an third party software available to read this KPI out of SAP/APO in a structured way

Thanks for your support, Markus

In my experience, you just have to learn to read the code. The SAP books may tell you something but they are not at the level that you'd really need them to be if you wanted to know where best to put your enhancement.
It is certainly worthwhile checking all the documentation in the classes/methods there can be some useful things there. However, generally I think you are just better off reading through the code and working out how it all hangs together. Most WDA code is reasonably well written - in that it is fairly modular and has a reasonable degree of encapsulation. This certainly helps.
This is where experience really starts to matter!
NW7.02 will give us some nice UML diagrams to help understand the application flow - that will help, but until then, it's just a matter of being good at understanding code.
Good luck.
