EWM inbound deliveries in STO process

We have an STO process, with materials with type A serial numbers.

Because of this, the incoming delivery must arrive at EWM with the serial numbers already reported: as if it were a Customer return.

Is it mandatory to report serial numbers to make the Goods Receipt?

We are finding that not all equipment is being updated correctly in S4: for example, the ERP inbound delivery is not being updated.
