We can just do CN Rebill (just to change the date of invoice to this month) so that Welltech have no issue to receive the order. You can just get approval from K Sansanee for this purpose as below :-

Dear K Sansanee
Seeking your approve CN & Rebill for order no. 930405727. This is due to the orders were rejected by Welltech due to shortage of carry case. YCH have received the carry case but Welltech is unable to accept invoice cross month.
As such, kindly also approve for the CN & Rebill for the order.
