You can define or edit the validity period of versioned propositions. The validity
period defines the life span of a proposition, that is, the time period during which that
proposition is active.
Note: New propositions or propositions with an undefined validity period (for example, legacy
propositions) are always eligible and do not expire. Propositions marked as inactive, or
propositions whose validity period has not started or has expired, are invalid.
-
In the header of Dev Studio, click .
-
In the Decision data records list, navigate to the group where
the proposition is located.
-
On the Data tab, click the name of the proposition that you want
to edit.
-
On the Create or update proposition form, click
Edit.
-
For the Active property, select the radio button that defines
the proposition validity:
-
Always - Make the proposition permanently eligible.
-
Never - Makes the proposition inactive (that is, disabled).
-
Within a defined time period - Makes the proposition active
within a particular time frame. Specify the Start Date and End
Date properties. The type of these properties is DateTime.
-
Click Submit.
The Active property of the proposition changes to True if the current date and time are
within the defined validity period or when the proposition is marked as always active.
Otherwise, the property value changes to False.

Click Save.
