Hi Onsima,
I had a short call with Khun Sukunya on the issue i) of the mail below. According to Khun Sukunya we have to establish different revenue accounts for different income sources. As cost accounts have to reflect also this split we have to establish also new cost accounts and book each single invoice (e.g. the invoice for services of Optimum) by using a %-key.
Could you please provide your thoughts about this requirement? Accounting table would be quite long if we have to do so. There is also the question on how to handle bookings from March to October: does Optimum have to do this split or will you care about this.
Regards,
Andrea
