11.5.10 Internal Fulfillment (Intercompany Transactions)

 Hello

I need to enable the internal fulfillment process (intercompany between 2 operating units) in 11.5.10.

I have the internal requisitions setups, however there are some difference to do the intercompany between 2 OU, hence I was wondering if you can share the prerequisites setup with me. 

Thanks
