Hi David,
As you have mentioned in the above, you have tried the currency conversion in 3.5 and working fine. Where as in 7.0 it is not working. Tell me on thing. Is there any upgrade happend for BEX that means it has been upgraded from 3.5 to 7.0 or no upgrade happend. Also let me know, are you able to execute the reports in 7.0 version or only executing the reports in 3.5. if you are executing thereports in 7.0 version then need to check the currency conversion in 7. version. Please clarify the above things then we will let you the solution.
Thanks,
