Hi Mark,
The following tables are updated :
- EKKO : header data
- EKPO : item data
- EKET : schedule lines (here you will find your delivery dates)
- EKBE : PO history (GR and IR)
- EKES : confirmations (if you have them)
- EKKN : account assignment data
There are more tables (for CO and PSM-FM, if you use it), but these are the most relevant.
Regards,
Freek
