How to detect changes in formula field value?

Hello!

 

I am trying to figure out a way through which I could trigger a workflow based on the value contained inside a formula field. I obviously can create a normal workflow, but that would allow me only to check the value at the instance when a record is created or edited. Is there any way of doing it EVERY time the value of a particular field changes?

 

Look forward to some encouraging solutions.

 

Best,

Pranav

Hi,

 

As of now, I could think of doing by Apex Triggers. Below is the sample code:

 

trigger CheckFormual on Account (before insert, before update) 
{
    for(Account a:Trigger.new)
    {
        if(system.trigger.OldMap.get(a.Id).FormulaFeild__c != system.trigger.NewMap.get(a.Id).FormulaFeild__c)
        {
            a.AnotherFeild__c = a.FormulaFeild__c;
        }
    }
}

 

In the above code, whenever there is a change in the formula feild I am populating that value to another feild. Likewise you can track.

 

 

Hope this helps.

 

Thanks
