Question:
Everytime when we make a change, the system will generate the Change number (i.e. if you go to PO -> Chanes history, you will see the number). But do you know what is the table use to keep all the change data? I think we can retrieve them based on the Change number.
Because in my PO, there is very interesting change. It say the partner VN has been change from A to B, then from B to A again... as far as I know, the VN is not changeable
Answer:
the tables are CDHDR and CDPOS, but you will probably not see any more info than you already see PO -> Change history
