Today, I query to Khun Lek (Accounting of GB) about quantity decreases for Skin Mill (Advance Payment).
Because when amount of skin mill decrease from the last month , its mean have used skin mill to production of Finish Goods .
GB should be deducted advance payment then charged the difference.
Accounting of GB (Khun Lek ) knows but does not deducted in first time.
She will be consultation with the authority for deduct next trading.
