RE: Purchase order discounts fields blocked
Hello Magno Pereira,
That's interesting that being a system admin; you are even not able to edit that!
Need to check the following;
--- Is there any customization made which could impact this ?
--- Have you set "Line discount", "Multi-line discount", "Total discount" for any specific item, item group, all items or for any specific vendor or vendor group in this path ? --- Procurement and sourcing > Setup > Prices and discounts > Activate price / discount.

If yes; then please check the data what you have entered in the PO, is not falling in this criteria.
Else; check for the following privileges, if after assigning them in user roles, is solving this case or not.
--- Edit prices and discounts
--- Maintain discounts
--- Maintain open purchase line discount journal lines
--- Maintain open purchase multi-line discount journal lines
Best regards,
Sourav Dam
