Returned Stock is not deducted from Customer Invoice in SAP Business ByD

[KhantNyi]

Hi Experts,

I want to ask about the customer return management scenario. For examples,

I am creating the sales order with 30 Quantities.

Then, I post the outbound delivery with full quantity.

Then, I am creating the New customer return notification to return the 10 of 30 based on that sales order. And post the goods receipt for the returned quantity. (Note: I am not posting the invoice at that time). And releasing the Returns as Without Credit Memo. And when I am trying to release the invoice request for that sales order, invoiced quantity is still 30 and returned quantity is not deducted and not editable.

Now my question is why the invoice request for that sales order is not reflect with that return documents. Cause I am processing the customer return before I execute the invoice posting. The customer receive their invoice with full quantity even though they have returned the 10 out of 30 does not make sense for me. Returned amount should be deducted from the invoice request. Please let me know if there is any functionality to correct the invoice request quantity along with the returned documents.
