Measure Factory Rule Types

Measure Factory includes the following rule types:

• Calc rule—Processes an expression that returns a value of any Spectre data type.
• Flag rule—Produces a Boolean value; similar to lookup rules but only one rule is used as the key in the lookup.
• Link rule—Allows movement of data from one data set to another.
• Lookup rule—Brings in information from a lookup file.
• Plugin rule—Runs an external process to produce rules not covered by the other rule types.
• Setup rule—Applies to version 7.1(13) and later. Created during the initialization of the data set, either from a data source or plugin.
• Source rule—Derives from the columns in the cBases.

In Workbench 7.1(13) and later, instead of using source rules, DI recommends that you either allow automatic import of all input columns or use setup-rule tags to explicitly define which columns are imported.
