Thank you. I realized that we have to use ZKLi for our own propose.
For this case, we would like to give 50 sets of tower rail as a premium/gifts at home sukkaphan dealer as they have campaign to stimulate sale out.,if end customer buy 10,000 Baht then get 1 tower rail for free.It seems to be more marketing cost/ETAT. Therefore we should use ZKL for this sale order, shouldn't we?
As FOC will reduce the CM1 and I don't want to cut it down, therefore I suggested team to use ZKLi at the beginning.
