MediaTek x20, lunch error

when I am running the command lunch full_amt6796_64_open-eng it gives following error.

~/develop/x20$ lunch full_amt6796_64_open-eng
build/core/product_config.mk:222: *** Can not locate config makefile for product “full_amt6796_64_open”. Stop.

** Don’t have a product spec for: ‘full_amt6796_64_open’
** Do you have the right repo manifest?

How to debug it?
