Hi Vadim Vdovin,
The option to receive a license plate in receiving company which has been packed and shipped by the sister company on inter company sales order is not as straight forward as it is for a transfer order.
If you will try and use the license plate receiving and put away then it will not allow you to receive the license plate for obvious reasons.
However this is possible where you can still receive the same license plate shipped by the sister company but not all at once. You can try and use the mixed license plate receiving option with source document line identification set as purchase order item receiving and put away.
Using this option you can scan the license plate on the mobile device and next you will be asked the purchase order number after which you have to manually receive the items as per license plate after scanning the bar codes.
This was you can still receive the license plate but not in the same fashion as you are able to do for transfer orders. There is no such functionality for purchase order as it is for a transfer order and its justified as shipping and receiving for a transfer order happens in same company and for same order.
Kindly see the below screenshot where i have received a license plate shipped on an inter company sales order.
