Dear Louis,
First of all i don't understand what does Kannika meaning on "I can post this month or not about 90880GAE0020 qty 820.2 of PO.8800013690".
If Kannika meaning that extra delivery, please take note to GR only the quantity in the PO, extra quantity will not be pay and supplier had agreed with that. PO will not be change too.
By the way, this issue had been delay for weeks, i had asked Kannika to check if the physical stock is correct as per supplier's advise but no reply since 30th June. Understand that GR need to done based on delivery order and actual receiving, however without knowing and getting the full info on what is deliver, these's no way for me to advise what to do.
cc Kannika, hope the above explain well
