The Analyst tool validates the lowest rule sets in the rule specification first. If the Analyst tool finds an error in a rule set, the Analyst tool stops validation and reports the error.

The Analyst tool reports one error at a time. When you repair a validation error, validate the rule specification again.

A rule specification can fail validation for the following reasons:

A condition or an action in a rule statement specifies a data type that differs from the input data type.
The rule statements in a rule set generate output data values of different data types.
A parent rule set does not read an output from a child rule set.
A rule statement is incomplete.

When you move or copy a rule set to another rule specification, you move or copy any test data that you added for the rule set. You also move or copy any input that the rule set uses.
