May I reply this email on behalf kha, To clearify the below please send Khun Mam the compare of the supplier on your hand (I do understand that you may have the compare on hand as you have to compare the price before order or PR or PO). Normally, for the approval we have to send the memo with supported documents to her and also, if you unable to convert to pdf. file please ask Khun Meng to assist kha.
BTW, before Purchasing manager leave she has been handed over her job to your team to handle/continue the job and GM has been decided you/team to take action on this during the time that we do not have purchasing manager or purchasing officer and I know that this is not your job description but I would appreciate, if you could help team to do this for smooth job kha.
