SAP Netweaver Gateway - oData - “Maintain Service Groups” not found

Dear Expert,

I'm new on Netweaver Gateway, I installed GW_CORE and IW_BEP in the same server.

I follow the guide How To Write an OData Channel Gateway Service. Part 1 - The Model Provider Class but I couldn't found "Maintain Service Group" and "Maintain Object Models" in my server.

Following is my SPRO screen shot and software component.

Installed Software component.

Please help.

Regards

Choong
