Hi experts,
My client (X) is a commercial company, they buy material A from Vendor and sell it for Customer.
my case is:
1. X buy 10 A from Vendor and add 1 A more for free ( I don't know which process I can use here?) (require: invoice receipt but no tax, no charge, no payment)
2. X sell 10 A for Customer and 1 A for free (I use Free goods process in SD) (require: billing but no tax, no charge, no ...)
3. Additional, how can I tracking Gas cylinder (in case X buy and sell Gas) between Vendor and Customer?
Plz help!
