The Previous field
After you enter a data point, traceability value, or standard on the data entry screen, the program moves on to the next prompt and, by default, displays the last value you entered in the Previous field.
For more information, see Viewing the previous entry.
Undo the most recent entries
Before a subgroup of data has been saved, you can undo one or several of the last values entered.
For more information, see Undoing one or more previous values.
