Some question about the renegotiation function in SRM Contract (GOA)

Hi All Expert,

We are on SRM 5/4.6, there is a question about the renegotiation function in SRM GOA.

Can we renegotiate the price for some parts in the GOA items with this function ( e.g. Only renegotiate one item in the contract) ?

Will the item price updated automatically after the renegotiation?

Many thanks in advance!!!
