Dear Jenny
I have to ask the team. They inform process as the followed step. But it may be possible to scan the bar code while they fall box that the scanner may not send data into the system, thus causing the error and the box may not scan. However, the inventory and searching we not found that goods left behind at BKK warehouse.
I have informed them attention to scan products fully count sticker printed in full amount. And labeling the sticker in completed and accurately.
