Inventory Item Group Setup "Inter-unit Payable & Receivable" fields

We were changing the inventory status of an item from “Quarantine” to “Available” and AX gave the following error message “Account number for transaction type inventory inter-unit receivable does not exist”. Does AX require that the Inventory Item Group setup fields “Inter-unit Payable” and “Inter-unit Receivable” be completed with account numbers? Currently those fields are blank. We are using AX2012 R3 CU12. Thank you in advance for your help.
