How I can automatically generate purchase orders in SRM?

Hi Gurus,

When I create a Shopping Cart (SC), in "Source of Supply" tab I can select a contract as source of supply.

How I can automatically generate a purchase order (PO) with contract data (vendor, price, etc.)? So that the operational purchaser does not have to enter the system to generate the PO.

In ERP (ECC 6.0) exists ME59N transaction, is there something similar in SRM?

The system is:

Component software: SRM_SERVER

Release: 700

Level: 0008

Support package: SAPKIBKV08

Thanks in advance and best regards,
