Mathematical Operation
If you intend to use a Mathematical operation step to calculate a date, you can reference both date-only and date-time fields. This is because mathematical operations are only performed against the date portion of date-time fields.
Mathematical operations are limited to adding or subtracting days, months and years to / from a date.
Note: A useful technique to perform date arithmetic using the
current date is to move the
global variable%CURRENT-DATE to a temporary storage
field and then perform the math on this field.
