Dear Doungsamon,
Thank you for your quick response. But there is still misunderstanding. Please see my input below:
1. First of all, for the normal process, do you need to send an invoice to Invoice process unit of Shell Hong Kong for payment? Please refer to below screenshot:
2. If so, could you help me check the amount of invoice which sent to Invoice process unit of Shell Hong Kong is 380 or 381?
If you have any question please feel free to contact me.
