Read Status Previous Value in Complaint
I am facing one problem.
When I am changing my complainet and saving it again at that time I want to read both Status of that complaint.
Suppose when I open complainet, status is Status1 and after change status is Status2. I want to compaire both the status.
I am able to read current status with CURRENT_VALUE method of collection_wrapper class. But I am also trying to read previous value for the same field status with PREVIOUS_VALUE method of collection_wrapper class. But it is returning blank .
I try so many other way but the problem is every time when page refresh, GET/SET method for that field updating value. I also try with CRM_ORDER_READ FM but that is also returning value based on current runtime version of the complaint.
Please suggest how i will read this previous value.
