You must use OCAF.

What does it mean by I must use OCAF. OCAF is a sample right? Why we can't implement this in the undo redo sample?

Hi Saneesh,
OCAF is the component of OCCT =>
See also OCAF User's Guide.
It supposes that you keep your information in attributes: Standard (available with OCCT release) or in your own attributes developed by yourself.
After that you may use Undo/Redo services provided by TDocStd_Document class.
