The Rule Options dialog shows the inconsistency error types. You can select from any one of the cells and change the value by selecting from the displayed list.
Inconsistencies
Inconsistency Type
There are six inconsistency types on the Rule Options dialog:
Inconsistent property value
When you add a new consistency criterion to a rule, the software uses the Status and Severity values you enter as defaults in the Consistency Tab (Rule Properties Dialog). You can then modify these default values as needed.
Inconsistent flow direction
Specifies the default Status and Severity where the software finds an inconsistency in the flow direction of the P&ID drawing. When you add the consistency criterion Flow Direction to a rule, the software uses these Status and Severity values as the defaults in the Consistency Tab (Rule Properties Dialog). You can then modify these default values as needed.
Unattached connect point
Specifies the status and severity where the software finds an unconnected piping connect point on a piping component, instrument, or nozzle.
Unattached connector
Specifies the status and severity where the software finds an unconnected end of a pipe run, signal run, or duct run.
No applicable rules
Specifies the status and severity where the software finds two connected items for which there are no rules that allow the connection. This can happen, for example, when you work with two different plants that have two different sets of rules. When drawing data is copied from plant A to plant B, using Assemblies or Import Drawings, items that were legally connected in drawing A might not be legally connected in plant B. Also, such an inconsistency might be generated if you edit a plant rule after drawings have been created based on that rule. If the drawings contain connected items and the rules that supported those connections are deleted, the result is connections that have no applicable rules.
Cannot evaluate consistency
When a pipe run, signal run, or duct run is attached to an Off-Page Connector (OPC) but no corresponding run is attached to the mate OPC, the consistency cannot be evaluated. This can happen when working in a project environment. Two drawings that contain an OPC and its mate might be complete in the As-Built plant. If only one of the drawings is fetched into the project, the consistency of the OPC connection cannot be evaluated because the other drawing does not exist in the project.
Status
This column has the following possible values:
Warning
The status is used to alert you of possible inconsistencies in your drawing. These
inconsistencies are of a non-critical nature. When you select this option, a Warning symbol 
displays on the appropriate drawing object. You can double-click the symbol to open
the Consistency Check dialog. On the Consistency Check dialog, you have the option to approve the inconsistency, and therefore leave it
in your drawing, or you can correct the drawing and remove the inconsistency.
Error
This status is used to alert you of critical inconsistencies within your drawing.
These errors must be fixed within the drawing for the inconsistency to be removed.
When you select this option, an Error symbol 
displays on the appropriate drawing object. You can double-click the symbol to open
the Consistency Check dialog for a more detailed view of the inconsistency.
Severity
This column can have numeric values from 1 to 10, with 10 being the highest severity. The software can be configured to show only those inconsistencies above a specific value. See the View Properties dialog.
