Dear K.Napaporn,
Thank you for your soonest feedback.
I’m understand now.
I understand the terminology of R/M is Raw Material, how about “Charge” and “Barrel”?
Is the “Charge” means “Process”?
Is the “Barrel” means “Mgt fee and Profit”?
Your kind support and explanation is really appreciated, thank you.
Best Regards,
Try David Sinambela
