Regarding the Tax invoices is lose so we ask supplier to certify the Tax invoice copy base on Tax authority rule and we accept this copy tax invoice. So the doc date that should refer to this invoice is the original doc that that supplier issued which is 05/09/2014 instead of the date of certify.
As when the suppler refer the invoice no. or date, they will use the original invoice and date, may I know what is the risk of using the original invoice date?
However the original posted was use the wrong doc date anyway.
