This function is only active when you make an entry that is not allowed.
It allows you to reverse the entries made in the row where the error occurred, thus returning the row to its last valid state in the planning session. The system then continues checking the entries with the next row.
This function (pushbutton ) reverses all the entries in the last dialog step. The system always stores the five last states so that you can restore these. However, these states are lost each time you switch from the overview screen to the period screen or back. After that you can no longer undo the previous step.
Note
If you choose this function by mistake, you can "undo" the "undo" using the
Redo
function.
The
Redo
function (pushbutton
) is only active after you have used the
Undo
function.
