How to build a report on what each wave has sales invoice?

Dear

We are trying to build a report on what each wave in wms has sales invoice

We can easily go from whswaveline to get the salesid which is the sales order number but i need to get the sales invoice

And that should be easy enough from the custjourtrans but my issue is that some sales order could be partially invoiced and divided on two waves

So i don't know how to link the sales invoice to a certain wave or shipment

Please advise how to get from wave to sales invoice?

Thank you
