Hiten,
If you know the time you start another modification then you could scatter current state to an object and gather later. ie:
Define class myModifier as Relation
Dimension arrModObj[1]
Procedure StartModify
With this
Dimension .arrModObj[iif(type('.arrModObj')='L',1,alen(.arrModObj)+1)]
Scatter name .arrModObj[alen(.arrModObj)]
Endwith
Endproc

Procedure RevertModify
Lparameters tlAll
With this
If type('.arrModObj')='L'
Return && No modification
Endif
If tlAll
Gather name .arrModObj[1]
Dimension .arrModObj[1]
.arrModObj = .F.
Else
Gather name .arrModObj[alen(.arrModObj)]
Dimension .arrModObj[alen(.arrModObj)-1]
Endif
Endwith
EnddefineNotice this is a simplified version that doesn't track recno() nor a redo option.
You could do that table wise with getnextmodified(). Also if table is small enough you could just copy to array whole table and get back too.
Honestly though I would use transactions or snapshot cursors (not SQL select-create cursor, do while getnextmodifed(),insert) if txnlevel() would be high.
