Hi,
Since you have already posted the revaluation, you might not be able to see the preview, if you have sandbox environment available with you, you can try with preview before posting, it will show the amounts with dimension combination.
As per MS document, before doing the revaluation, system will make the combination of Ledger account wise balances and then with new exchange rate, it will suggest the Exchange rate gain or loss.
In most of the clients, there are many other financial dimensions as well, so combination can get so large, so to avoid that situation, Microsoft introduced the new feature "Enhancements to bank foreign currency revaluation" , that gives the option to reset the existing foreign currency revaluation done till date.
It gives the option to define Financial dimension to be taken as All or None, if you choose All, it will have same behaviour which is happening now, in order to generate consolidated entries for bank currency revaluation, it gives you option to select "None".
As suggested by @Andre , to get the detailing about already posted transactions, you need to export the dimension wise data, OR you can also do some mathematics with current posted voucher, and trial balance generated on revaluation date.. you will get the simulation as shown in first screenshot.
In case of any further queries, please let us know..
