Set a partially invoiced Sales Order as Completed

Dear Experts,

I would like to know if there is a way to set a partially invoiced Sales Order as complete without any financial impact.

This case involves a Sales Order which was fulfilled through multiple deliveries. Two Outbound deliveries were executed, and only the first one was invoiced. I would like to set the Sales Order as complete anyway, without invoicing the goods that are related to the second Outbound delivery, and without any financial impact.

How could this be performed?

Many thanks in advance,

Regards
