PartActivateInvoice should be used when the complete order isn't ready to be shipped, but only a part of it. This way, the invoice that's created only contains the stuff you've actually sent and the customer doesn't need to pay for something they haven't received.
In short, if the complete order is ready to be sent, use the ActivateInvoice request. If only a part-delivery can be made, use the PartActivateInvoice request.
If using the PartActivateInvoice request, a new pending invoice will be created for the remaining invoice rows. In the response, this new invoice will be given a new invoice number (NewInvoiceNo). When it's time to activate the remaining invoice rows you can use either the ActivateInvoice or the PartActivateInvoice request, depending on if everything's ready to be shipped or not. Please note that the request should use the NewInvoiceNo value and not the original one.
