Running the Rules Check command in IDEF3 process modeling

You can use the Rules Check command to search a diagram for rules violations-for example, Links (Line Symbols) that have not been defined, or UOB's (Unit of Behaviors) that lack process description definitions.

1 Open the diagram you want checked, pull down the Reports menu, and select IDEF3 Rules Check. You will see an on-screen report, detailing any errors found. For each error, the report gives the rule number, a brief explanation of the violation, and the name and type of the symbol in error. Rules Check also flags the errors directly on the diagram. For each error, you will see a circle at the lower right corner of the offending symbol, with a rule number, such as R1, in the middle of the circle. If more than one error has been found for a symbol, an asterisk is added to the rule number. These additional errors are listed on the report along with their explanations.

2 To print the report, right click on it. From the Floating Menu, select Print. (You can also use the Print icon or File, Print.)

3 To clear the error flags, pull down the Reports menu and click on Clear Errors.
