I want to make a formula to my calculated column :
If the DD Rating is High => Add 3 months to the [DD Sign-off Date] If the DD Rating is Medium=> Add 6 months to the [DD Sign-off Date] If the DD Rating is Low => Add 12 months to the [DD Sign-off Date]
So the formula must be like this :
=IF([DD Rating]="High",
TEXT(DATE(YEAR([DD Sign-off Date]),MONTH([DD Sign-off Date])+3,DAY([DD Sign-off Date])),"dd/mm/yyyy")),
IF([DD Rating]="Medium",
TEXT(DATE(YEAR([DD Sign-off Date]),MONTH([DD Sign-off Date])+6,DAY([DD Sign-off Date])),"dd/mm/yyyy")),
IF([DD Rating]="Low",
TEXT(DATE(YEAR([DD Sign-off Date]),MONTH([DD Sign-off Date])+12,DAY([DD Sign-off Date])),"dd/mm/yyyy"))
DD Sign-off Date
is required column?
