Here you can find & set the internal customer (right hand side).

With the suppliers it's the same on the supplier page under the purchase tab

Hi @Deepak ,

I assume you have already made the configuration needed for the intersite process, right?.

If so, then your internal customer will be the one associated to the purchase site (i.e. the site where the internal PO is created). Also, you can check the internal customer by checking the Supply Chain Order Analysis in the PO line. In there you will see the Incoming customer order and/or Customer Order created for corresponding internal customer.

I hope this helps!

Regards,
