Original value of a changed attribute

Hi Experts,

Can you please let me know the way to find the original value of a changed attribute?

eg: I have an attribute "NAME" and the original value: ABC

Now, I changed the value to: DEF and click save. At this point of time how do I get the original value ABC before the actual save/commit happens.

I tried the method "IS_PROPERTY_CHANGED" in the class: "CL_CRM_BOL_ENTITY" but doesn't seem to be working.

Thanks in advance.
