Partial shipment inquiry

Hi everyone,

May i ask for your help/insight with regards to this kind of inquiry in Sales Order > Shipment module

Scenario:

I got two different SO transactions(SO#014067 & SO#014068) in one Shipment transaction, then I made the first shipment  of SO#014068 all the way to invoicing and payment of it, then the status of shipment transaction is Partially Invoiced.

Now, my question is how can I edit the Shipment QTY(because I want to ship some SO lines in a partial) or how can the CORRECT SHIPMENT field can be use in this kind of scenario?

Please any insight will be appreciated
