IR/ISO Accounting Issue

Hi All,

We have to set up the IR/ISO Cycle. We had done the basic setups and are able to create IR and ISO in respective operating units. Now we have involved the finance team and are looking into the invoicing aspects. As we understand AP Invoice will be created in the IR operating unit and AR Invoice will be created in the ISO Operating unit. To establish this should be have to setup intecompany relations? In inventory module along with shipping networks.

If no, then what is the significance of Intercompany Relations for IR/ISO Cycle?

Regards,
