This Invoice under month April 15.
Our record SSG Invoice 6604 versus our PO number, qty and glass type is correct.
We check and re-check many times on our record.
Please note, we are checking our own record for PO and Packing List and not the GR, since there is a issue since May on inputting and we all understood not able to reverse or revise.
Maybe you can re-check again previously is it correct the GR inputting to the correct PO and into correct GR?
It might be help you to solve this issue.
