BL correctness issuing is our basic KPI's department. If as you need to get information to complete a preliminary injunction from the CS.
For the case, basically our BL team was not received any instruction, since overseas return to CS for revision, moreover she done it by herself without noticed until invoice settle require.
From now onward I have strongly instruct to my team that if their have any suffer for new port or unclear from SI, they will back to me before issuing BL.
