Local purchasing group in the creation of a shopping cart

Hello everybody,

I'm working on SRM about shopping carts. When I create a shopping cart, the purchasing group is a local group, and no purchasing organisation is available. In fact, I want to be able to modify these elements and specially I want the values corresponding to the elements of the enterprise structure (PPOMA).

Could you help me please?

PS: the organisational elements correspond to the elements of the enterprise structure when I create a purchase order
