As advised, I connected to site and went over with Supakit Chuysakul, (+6676-362999) over phone and Bomgar chat with all the details of the two cases, credit note, output tax report and showed him the reservation as to why its showing a 0 non-vat.
He tried reaching out to the Finance but could not find anyone there, so he said he will discuss with Finance on this issue and get back to me on Monday. I advised him to get all information from what accounts is looking for to do with the reports.
When you have all the information as the subcase already close? Please give us all detail that Sreedevi asking for.
