I'm sorry but maybe I misunderstood...
According to the today's latest chart(Rev.5) from Nattawat-san, I guess that you could manage to shuffle your shipping schedule around.
So, the Q'ty we need to ship to you is as below, right?
Due Q'ty Remark
27-Aug 900 pcs Already shipped
10-Sep 2,340 pcs
24-Sep 1,620 pcs
(See attached file: 20140821_AFM Delivery plan August'14-Oct'14(Rev.5).xls)
We will do our best to keep up the above schedule, at least.
In addition to it, we will do our best to hasten our production as much as we can, to avoid zero stock on 6-Sep.
Also, due to this flucutation, the POs become messy, so please fix it later.
If you have any question or requirement, please let me know.
Thanks,
