How to display/enhance entity type properties from a data model

Hello,

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 it in its include  /SRMNXP/INCL_CUS_MINISC_HDR.

In SEGW, i created a Z project and i imported the above ABAP structure: now, i have my Z entity type with the new property.

Nevertheless, when i run the application, my new technical name does not make part of the properties.

What am i missing?

Thank you for your help.

Regards.

Laurent.
