Business rules for change start and end date and change tasks

Hello everyone, I would like to create a BR so that when the user changes the date of start/end the change, I can check if the dates of the change tasks are within the dates (start/end) that were filled in, so that if they were not, send an alert to also change the dates of the tasks, I don't know exactly how to do it.. could someone help me?

I created this script but it sends the alert regardless of whether the dates are correct or not.

 

 

 

(function executeRule(current, previous /*null when async*/ ) {
var areDatesWithinRange = function(startRangeDate, endRangeDate, dates) {
for (var i = 0; i < dates.length; i++) {
if (!dates[i])
continue;
if (gs.dateDiff(startRangeDate, dates[i], true) < 0 || gs.dateDiff(endRangeDate, dates[i], true) > 0)
return false;
}
return true;
};
var gr = new GlideRecord('change_task');
gr.addEncodedQuery('change_request='+ current.sys_id);
gr.query();
if(gr.next()){
var StartDate = gr.planned.start_date.getDisplayValue();
var EndDate = gr.planned.end_date.getDisplayValue();
if (!areDatesWithinRange(StartDate,EndDate ,[current.start_date,current.end_date,])) {
gs.addErrorMessage(gs.getMessage("Test"));
current.setAbortAction(true);
}
}
})(current, previous);

Hi,

So if I understand this correctly, you want to evaluate if the start and end date of attached change tasks are within the same range as the parent change record.

Then I would write a business rule that runs on change_request table, with condition as start date or change date changes, and in the script write something like this:

 

(function executeRule(current, previous /*null when async*/) {

	var changeTaskGR = new GlideRecord('change_task');
	changeTaskGR.addActiveQuery();
	changeTaskGR.addQuery('change_request', current.getUniqueValue());
	changeTaskGR.query();
	
	if (!changeTaskGR.hasNext()){ // no tasks found
		return;
	}
	else{
		var changeStart = new GlideDateTime(current.getValue('start_date'));
		var changeEnd = new GlideDateTime(current.getValue('end_date'));
		while(changeTaskGR.next()){
			var taskStart = new GlideDateTime(changeTaskGR.getValue('planned_start_date'));
			if (taskStart.before(changeStart)){
				gs.addInfoMessage('Change task is set before change start: ' + changeTaskGR.getValue('number'));
			}
			var taskEnd = new GlideDateTime(changeTaskGR.getValue('planned_end_date'));
			if (taskEnd.after(changeEnd)){
				gs.addInfoMessage('Change task is set after change end: ' + changeTaskGR.getValue('number'));
			}
		}
	}

})(current, previous);

Script:

(function executeRule(current, previous /*null when async*/ ) {

    // Add your code here
    var plannedStartDateChange = new GlideDateTime(current.start_date);
    var plannedEndDateChange = new GlideDateTime(current.end_date);
    gs.log('Planned Start Date is ' + plannedStartDateChange + ' and the Planned End Date is ' + plannedEndDateChange + ' on the change ' + current.number);

    var changeTask = new GlideRecord('change_task');
    changeTask.addQuery('change_request', current.sys_id);
    changeTask.query();
    while (changeTask.next()) {
        var plannedStartDateCTask = new GlideDateTime(changeTask.planned_start_date);
        var plannedEndDateCTask = new GlideDateTime(changeTask.planned_end_date);
        gs.log('Planned Start Date is ' + plannedStartDateCTask + ' and the Planned End Date is ' + plannedEndDateCTask + ' on the change task ' + changeTask.number);
        if (plannedStartDateCTask == '' || plannedEndDateCTask == '') {
            gs.addErrorMessage('The CTask ' + changeTask.number + ' is having empty value in Planned Start Date / Planned End Date');
        } else if (plannedStartDateCTask >= plannedStartDateChange && plannedEndDateCTask <= plannedEndDateChange) {
            gs.addErrorMessage('It\'s within Range');
        } else {
            gs.addInfoMessage('Error! Not within Range');
        }
    }


})(current, previous);
