Hello Wendy,
Looks like you were looking for an answer 2 years ago!
IBIS Prof. Thome AG based in Wuerzburg, Germany created Reverse Business Engineering (RBE) for SAP systems in the 90's. Now that technology is called RBE Plus.
Together with SAP, IBIS used this RBE Plus content to create Reverse Business Process Documentation (RBPD) to automatically generate a Business Blueprint.
However, for BW systems we have the traditional RBE Plus for SAP Solution Manager that can be used to automatically generate a Business Blueprint of the BW objects - which can then become a Template Project.
If you're still looking for something, please let me know.
Best Regards,
Marci Braybrooks, IBIS America
