Issue with Current Value and Previous Value

Hi,

We have couple of attributes which are free text. Now when we are changing the value of these attributes then in the attributes applet we can see the present value is coming in the current value field and previous value field.

Now we need to have a batch job run based on the validation on these fields.

As per our understanding these fields should have different values similar to Service Num and Prev_Service Num fields.

Please suggest if the understanding is correct and whether it is a open issue and how to resolve this.

We are using IP2015.
