trigger requirementsTrigger on Requirements__c (after insert, after update) {
List <Id> progIds = new List<Id> ();
List <Programs__c> programs = new List<Programs__c>();
List <AggregateResult> requirements = new List<AggregateResult>();
for(Requirements__c req:trigger.new){
progIds.add(req.Programs__c);
}
programs = [Select Id, Count__c From Programs__c Where Id In :progIds];
requirements = [Select Programs__c, Count(Id) From Requirements__c Where Programs__c IN: progIds
AND Waived__c = 'Yes' AND Status__c IN ('Active')
Group By Programs__c];
for(AggregateResult ar: requirements){
for(Programs__c p:programs){
if(ar.get('Programs__c') == p.Id){
p.Count__c = Decimal.ValueOf(String.ValueOf(ar.get('expr0')));
}
}
}
update(programs);
}
please add below debug and check value once.
system.debug('===='+Decimal.ValueOf(String.ValueOf(ar.get('expr0'))))
Please add program to list and update the list.
