need to enhance entity type properties from data model



i work on "My Shopping Cart" SRM Fiori application.

I need to add a customer field among an entity type's properties. The ABAP structure type name is /SRMNXP/S_SC_HEADER: i added my CUF in its include /SRMNXP/INCL_CUS_MINISC_HDR.

In SEGW, i created a Z project and i redefined the SAP GW OData technical service name /SRMNXP/SHOPPING_CART.

Then, i imported the properties from data source in order to add my CUF.

Finally, i generated the runtime objects (artifacts).

Nevertheless, data provider base and extension classes failed due to syntax error (The final class "/SRMNXP/CL_DATA_ACCESS_BASE" cannot have any subclasses).

What am i missing?

Moreover, after solving this point, is there any other steps to realize?

One final question: where can i look at standard entity types for a technical service (as the way displayed in SEGW after OData service redefinition?)

Thank you for you help.
