A sheet processing apparatus includes a sheet storage unit configured to enable itself to be opened and closed and a display unit configured to display a screen for setting an attribute of a sheet stored in the sheet storage unit. Whether or not to display the screen for setting the sheet attribute is determined based on a remaining number of sheets obtained before the sheet storage unit is opened and a remaining number of sheets obtained after the sheet storage unit is closed. The setting screen is displayed on the display unit based on a result of determination.
