English to Swedish Bus/Financial Engineering (general)

I ett anbud för en kunds upphandling av tåg och tågvagnar som jag översätter står det så här i kapitlet om nyckelpersonal
och ansvarsområden i avsnittet om upphandlings- och logistikchefens olika allmänna ansvarsområden:

Project Procurement and Logistic Manager
He is responsible for managing and coordinating the procurement stage in order to meet the Project Schedule.
He provides leadership to the procurement team, guiding the team to an on time procurement that meets the schedule.
Between others, his tasks are:
Manages the correct execution of the procurement management plan (see Additional Information P-11.2 Preliminary Procurement Management Plan).
Review proposals received from potential suppliers.
Manage the details of the purchasing order once it is placed.
For other than MSIs, place the purchase order.
Set the necessary processes in motion to ensure that all orders sent to suppliers reflect the delivery dates shown in the ERP (Enterprise Resource Planning) management system.
In case of non-conformities, make the final decision about what will happen to the material: accepted by concession, scrapping or recovery.
Report in Project Review Meetings about the status of the procurement stage and supplier’s lead-times.

(MSIs förresten syftar på Större utlagda projektobjekt.) Och den engelska källtexten är fel på ett ställe, "Between others" betyder förstås Bland annat.

Men vad betyder Accepted by concession? Om materialet inte uppfyller uppställda krav ska det skrotas, återvinnas eller Accepted by concession.
