Publishing Measures
The published GA measures can be divided into the following categories:
Read only—can only be used on the right-hand side of the expression
Writable—can be used on both the left-hand side and right-hand side of the expression
RuleGroupOnlyWritable—a specific measure that can be read/written in the specified rule group
Loadable—measures that can be loaded using OAT and can be present in the custom load batch control file
WorkbookMeasureOverride—measures which property can be overridden in the associated workbook
ReadableExecutionSet—list of GA batch control execution set names that can be called from within a custom batch control execution file
The list of published measures will change based upon configuration. Therefore, the list is dynamically generated at each configuration regeneration.
The contents of the list are saved in a file named: publishedMeasures.properties. 
               
The file is located under [config]/plugins. Before writing custom rules, regenerate your application configuration
and then open the file to search for published application measures.
