help on custom objects using trigger....
this is my query...plzz help me out...
¢Create a custom object “Revenue”. Create a field named “Total Revenue”.
¢Create another custom object Revenue Line Items. Create field named “Add Revenue” and lookup to Revenue.
¢Create a trigger on Revenue Line Items to update “Total Revenue” field on Revenue with the total(sum) of “Add Revenue” on all child records to the parent revenue record.
¢Handle insert, update and delete. Also handle change of parent revenue on child record.
BRIEF SUMMARY :
suppose “Total Revenue” = 30 and “Add Revenue” = 20...if i add 10 in “Add Revenue” than
“Total Revenue” should become 40 automatically and if i subtract 10 from “Add Revenue” than
“Total Revenue” should become 20....
Any help would be appreciated....!!!
Hi you can do it By Roll-up summary also
But if you need to do by using trigger.
Write a trigger on child (Revenue Line items) object
Here i am posting one trigger just replace fields and objects
Revenue -- Example2__c
Total Revenue -- Total_Amount__c
Revenue Line Items -- ChildExample2__c
Add Revenue -- Amount__c
trigger Testduplicate7 on ChildExample2__c (after delete, after insert, after update) {
set<Id> Ids = new set<Id>();
if(trigger.isInsert || trigger.isUpdate){
for(ChildExample2__c p : trigger.new){
Ids.add(p.Example2__c);
}
}
if(trigger.isDelete){
for(ChildExample2__c p : trigger.old){
Ids.add(p.Example2__c);
}
}
map<Id,Double> smap = new map <Id,Double>();
for(AggregateResult q : [select Example2__c,sum(Amount__c)from ChildExample2__c where Example2__c IN :Ids group by Example2__c]){
smap.put((Id)q.get('Example2__c'),(Double)q.get('expr0'));
}
List<Example2__c> ls = new List<Example2__c>();
for(Example2__c a : [Select Id, Total_Amount__c from Example2__c where Id IN :Ids]){
Double PipelineSum = smap.get(a.Id);
a.Total_Amount__c = PipelineSum;
ls.add(a);
}
update ls;
}
