From July onwards, we still keep the practice below to reject the payment to the invoices which have wrong coding to avoid the delay payment at the second week of the month to the rest of vendors. However, we got approval from higher management level to have the second round at around 4th week of the month to make a payment to aforementioned rejected invoices from the first payment round, effective from July onwards.
Thus, all rejected invoices will need sites assistance to communicate to the SSC team to correct them within 1 week after A/P informed you with cc myself in the loop to let those invoices are unblocked and included in the second round of payment of the month.
Kindly let me know if any further questions occur.
