Dear Khun Padnarin,
For your issue DN/(CN) from VNT to ABT in the future,please change due date to end of the next month to prevent misunderstanding and over due problem in SAP.
Dear Khun Naritsara,
In the case, I understand the it was just in case DN/(C/N) only which usually we will use due date is end of next month same invoice but this case i assume the system generate automatically due date,so we have to change manually before post these DN/(C/N).
Dear P'Nongluck,
Do you have other comment? and if I misunderstood,please suggest krab.
