Trigger update problem
Hi..
I have write one trigger for custom object Project__c. When I update Savings__c field that value is added into another custom object field Work__c.Overall_Savings__c..
I want to know fetch before update value and after update value..
That is
before update Savings__c =5
After update I have changed into 10
means how can I fetch 5 and 10..
because before update overall_savings__c =50
After update Overall_Savings__c =55
That is I have to add just difference value to Work__c object field Overall_Savings__c...
Any one have a sample code please post me
For your issue you can use: Old and new trigger values.
Eg. trigger.new.Savings__c and trigger.old.Savings__c for retrieving the new and old values respectively.
Hope this solves your problem.
