Once you run the revaluation and see that there are two ways you can correct a revaluation.
1. You can reverse the revaluation.
2. You can re run the revaluation.
This depends on on which type of incorrect revaluation is made.
If you revaluate the wrong account or want to record the incorrect revaluation, it is better to cancel the revaluation.
But I found it better to revaluate again if it is just because of the incorrect exchange rate.
This actually depends on the consultant that does the implementation.
