Due to you inform are mistaken route.
True rote : Supplier -> Purchase JKOT -> Procurement Japan -> ENG -> Procurement Japan -> Purchase JKOT -> Supplier.
Which cannot approve by in-house JKOT.
In addition supplier input data miss 2 item
1.Input data not full detail.such as plan do it and another.
2.Do not sign approved from engineer in-charge.
So please kindly to know and action also.
If has any question please directly tell with Ms.Nopawan.
She best understand this detail.
