Hi
This can be acheived using the Field selction control.
Check the field selction key for the PO document type.
SPRO-> Materials Management-> Purchasing-> Purchase Order-> Define Document Types.
Now maintain the filed selction key in
SPRO-> Materials Management-> Purchasing-> Purchase Order-> Define Screen Layout at Document Level
In the filed selction group Terms of delivery and payment, maintain the field selection option as display for the fields
Terms of payment
Terms of payt. (days, percent)
For the field selection key ME21N & ME22 also maintain the same
Thanks & Regards
