Maintain a validity combination

If required you can change the start and end date via the Properties of the validity combination; you cannot change the calculation bases.

Note:

When you need to change a validity combination, we recommend that you create a new one, and not that you change the existing one. By doing so, you will create a history of the combinations so that you can always check which validity combination applied on which date. You can use multiselect to add an end date for several validity combinations at the same time.

You can also Delete validity combinations.
