Problem creating operation assignment in ESR Model

Question

I am trying to follow the step-by-step instruction from Franklin Herbas's blog - https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/8018. [original link is broken] [original link is broken] [original link is broken]  It worked fine initially but I ran into problem when double-clicked on the small round icon on left-bottom side of the operation in the model, a window did pop up confirming creating object for the operation.  But when I clicked on Create, nothing happened.  No operation is created in the service interface.  I have checked and there is no error in the Java log.
Any idea what I may have done wrong?  I am running on ESR 7.1 SP4 on CE 7.1 SP4.

Jiannan

Hello Jiannan
Regarding the first problem that you faced - Once you have done create assignment, use the open assignment option and see if that creates the operation. That should work.
Secondly, for stateless being grayed out, please open the Software component version properties (by double clicking on the Software Component version) and there you have an option of choosing the "Use of Interface Objects" - Please choose SAP NetWeaver 7.1. If you choose SAP NetWeaver 7.0, it means all your content in the Software Component Version should be 7.0 compatible.
In other words, your service interfaces should have only one operation and patterns such as (Stateless, Stateful) are not enabled.
Hope that clarifies your doubts.
