Christian, Normally, when goods are received and subsequently rejected by the QA/QI department an RGA/RMA needs to be negotiated with the supplier and received. Otherwise there would not be any legal grounds for getting a reimbursement for faulty products.
In the scenario you outlined the following could/would apply: - receive 100% of the goods and put in inventory - get RGA/RMA for faulty products - do a return for faulty products (state RGA/RMA) - get credit note or replacement products. OOTB this functionality is available. Therefore no adjustments on entity model are required.
