Trigger on Date

I need to create a trigger where (tot.Date_vod__c < (THIS_YEAR(system.today())-1-11))

I want to avoid users from deleting TOT with Date_vod__c that is less than Jan 11 of this year

I am not sure if I am doing it correctly.

    Hi Carmilyn,

    Try using a simple trigger like this.

     

    trigger TOTTrigger on TOT (before delete) {
    	for (TOT deleteMe : trigger.Old) {
    		if (deleteMe.Date_Vod__c < Date.NewInstance(Date.today().year(), 1, 11)) {
    			deleteMe.addError('Meaningful Error Message.');
    		}
    	}
    }

    The above code basically checks compares the date on the record to Jan 1 of this year. If the record has a date thatless than that then it will result in error.

    Hope this helps!
