Regarding the behavior of credit-only returns orders

Summary:

When I entered a credit-only return order, the step was to perform the receiving process, and when I accepted the return, the situation was that inventory was recorded.
Normally, in the case of a credit-only return order, the invoice should be linked to AR after the order is registered, but why was it necessary to carry out the return acceptance process and also record the inventory?
Additionally, even though we have accepted the return, the status of the order details remains "Waiting for acceptance".
