Error ORA-01741 when editing table (F4)

Thanks for answering, I always had problems and I only had to solve them via commands (Update, Insert, etc.)
Good that it is already mapped to be corrected.

Thank you and have a nice day.

Note: I described another possible error in the following link and I do not know if they have read it, I pass it to them in case they consider it important.
Option problem: Desktop SQL o PLSQL
