FavoriteBruce MacLennan (Glenduir) asked in #Data ManagementFeb 3, 2014, 12:54 PMReferencing the start date of a custom fiscal period in a formulaHow do I add a validation rule to an Opportunity Close Date to ensure it is in the current fiscal period? I found this formula: AND( OR ( ISNEW(), ISCHANGED( CloseDate )), CloseDate < DATE( YEAR(TODAY()), MONTH(TODAY()), 1) ) this doesn't work when the start date of a fiscal period is say 30 March.4 answersSortSort by DateSort by Most HelpfulSort by DateLoad more comments...Bruce MacLennan (Glenduir)Feb 3, 2014, 2:31 PM Phil, that's very interesting, thanks.Add a commentWrite an answer...BoldItalicUnderlineStrikethroughBulleted ListNumbered ListAdd linkCode blockInsert imageAttach filesLink URLCancelSave0/9000Reply
