Recently while doing implementing SRM 7.2 at the client site, we got a requirement where business user wants SAP SRM Shopping cart with limit and free description having same supplier should create one PO with differnt lines. But as a standard system is splitting the Shopping Cart into two different POs.
To achieve this functionality a new enhancement needs to be created, which will create a single Purchase Order for Limit and Free Text line item Shopping Cart.
