Rule Specification Properties

Rule Specification Properties

A rule specification has properties that you can view and edit in the Developer tool. Use the properties to review descriptive metadata for the rule specification name. You can also use the properties to determine the number of output ports that the rule specification generates for downstream mapping objects.
To view the properties, open a mapping that contains the rule specification and select the rule specification icon. Then, select the
Properties
tab in the mapping.
The tab displays the following views:
General
The general properties contain the name and description of the rule specification instance.
If you update the rule specification name or description in a mapping, the changes that you make apply in the current mapping only.
Properties
The properties include the rule specification name that appears in the General view. The properties also specify any date range that an Analyst tool user set for the rule specification. The date range indicates the interval during which the rule specification is valid for use.
You can select or clear an option to allow an output for each child rule in the rule specification. A child rule is a rule set in the rule specification. When you select the option, the Developer tool adds an output port for each rule set to the rule specification in the mapping. The option is clear by default. Select the option to make available the rule set outputs to downstream objects in the mapping.
Ports
The port properties list the input and output ports on the rule specification instance. The port properties display the name, data type, precision, and scale of each port. You can optionally add a description to a port. The description applies to the port in the current rule specification instance.
Run-time Linking
The run-time linking properties determine now the rule specification ports link to other objects in a dynamic mapping.
Advanced
The advanced properties include the tracing level setting. The tracing level defines the amount of detail that appears in the log for the rule specification. You can choose terse, normal, verbose initialization, or verbose data. The default value is normal.
