Cannot create Fiscal Period/Calendar from 10 years ago and beyondIssue When generating a Fiscal Calendar, by default, Fiscal Calendar cannot be created from 10 years ago and beyond, or past 20 years in the future. Release All Cause This is by design Resolution To generate a Fiscal Calendar/Period with greater range, below workaround can be applied. Beware that below workaround is a customisation. Tests in Non Production instances are recommended, and that the records are recommended to be reverted after applying the workaround. 1) Script Include 'ITFM_FiscalCalendar' https://{Instance}.service-now.com/nav_to.do?uri=sys_script_include.do?sys_id=eb107e47cb03020005ee77a4634c9c2a Add the following code in the script include: getFiscalYearForChoose: function(){ var yearArray = []; var gdt = new GlideDateTime(); var currentYear = gdt.getYearUTC(); for (var i = currentYear - 20; i <= currentYear + 20 ; i++) { //You can change the number of years before/after current year here yearArray.push(i); } return yearArray; } 2) UI Page 'generate_fiscal_calendar' https://{Instance}.service-now.com/nav_to.do?uri=sys_ui_page.do?sys_id=4fb47130cb30020005ee77a4634c9c89 Make the following changes at line 49-51 of the HTML: Change:<g2:evaluate var="jvar_yearForChoose" jelly="true" object="true"> JSON.parse(new SNC.FiscalCalendar().getFiscalYearForChoose()); </g2:evaluate>to:<g2:evaluate var="jvar_yearForChoose" jelly="true" object="true"> new ITFM_FiscalCalendar().getFiscalYearForChoose(); </g2:evaluate>
