When this special function is activated, the user is supposed
to enter scrap reportings in kilos instead of pieces. The standard
button for reporting scrap is hidden, and a new button with the text "Scrap, KG"
is shown.
The
scrap
reporting performed
is recalculated using the formula "Entered value / alternative_unit2_recalc_factor"
where the factor is retrieved from the work
order row. (If none is supplied there, "1" is used.)
