Choose the Against value option for the type of value you want to check. The following options are available:
-
Select Attribute and then select the attribute you would like to check by clicking the ellipsis (...) button and selecting the appropriate attribute for the Attribute field.
When configuring a System Task, the Previous check box is enabled. This option allows you to get the previous value of the specified attribute from the current object. If this option is not selected, the current value is used.
-
Select Property if you will be setting the checked value in a named property. Specify the name of the property in the field.
-
select Constant if you wish to provide a constant value to check against. Provide a value in the field.
The following is an example of how this rule could be used. Datasets are configured to divide the 50 states into regions, where each dataset is named for the region and all the states of that region are values in the dataset. To test an object that has a State attribute to see if it is in the “Southwest” region, a Dataset Contains rule can be created specifying the Southwest dataset and the object's State attribute.
