Doc date on PO
If a PO is created on 09/12/2008 and saved and then again changed on 09/20/08 and saved. Which date will doc date on PO reflect and where I can see the dates where changes have been made!!
As mentioned above, PO creation dates remains the same. Regarding changes, they are stored Change Document tables CDHDR and CDPOS. You may see them using ME23N->Environment->Header Changes/ Item Changes.
