I agreed with your.Per our talked the main issue is came from
1.No stock part in inventory.
2.No one order this part to support production line
3.In SAP system. It's mixing 2 part in part no. So, need to urgent to clarify.
4.The NC parts AIPR already cooperate with customer to accepted to used.(This Gray Foam was used since start mass.).But the order from 18/Oct/16 on must be use black foam.
So,we must focusing on item#1, item#2 and item#3.
