assuming that you are working with excel DDT drive you can not go back in the loop.
technically this is not TC limitation it is Ms-excel limitation.
But you can use different technique , store previous row in an array https://www.w3schools.com/asp/func_array.asp
0) define an array before you call DDT drive
1) in your loop just before Call Driver.Next() , store your XL values in array
2) In your xl values processing area put an IF condition like... if fails use array values.
I concur that, if you need to re-use values of the current row for some reason, simply store those values in some structure (object, array, variables, external file, etc)... that is if you need to cycle back through. However, as long as you are still in the same iteration of the DDT loop, then you can just keep re-using the values until the loop recycles.
