Dear Kathryn,
I can not agreed in this case because the invoice no. I121551 we are not recieved material but
do you have charge us.
It this case it have effect for custome department of Thailand the random recheck for import material to Thailand.
So, We need change quantity and amount for record in SAP system and credit note please change the reference the invoice.
It is correct and clear for this case. I will process the payment to you.
I hope you are understand in this case.
