Use
You can use the operator IN to define lists of values that have an OR relationship to each other.
COLOR IN (‘red’, ‘yellow’, ‘green’)
If you use a condition like this as, for example, a precondition for a characteristic, the characteristic appears if the value assigned to characteristic COLOR is either ‘red’, ‘yellow’, or ‘green’, or if no value is assigned to characteristic COLOR.
LENGTH IN (200, 300, 350)
If you use a condition like this as, for example, a selection condition for a BOM item, the item is included in the BOM explosion if the value assigned to characteristic POWER is 200, 300, or 350.
