The records in the Calendar Type Setup window populate the Default Calendar Rule drop-down list that appears in the Custom Calendar window. The Custom Calendar window defines each custom calendar, subject to manual user override on a day-to-day basis. Each Calendar Type in the Calendar Type Setup window is defined by a Calendar Hours Groovy script, these scripts are created and maintained in the Groovy Scripts window. At times, it is necessary to adjust or add a custom Calendar Groovy script. This is done in the Groovy Scripts window under the Calendar Hours Groovy script type. Once a Groovy script is added here, then it will appear in the Groovy script drop-down list on the Calendar Type Setup window.
