Problem with Primavera Export from P6v7 to P6V8.3.2

Hello There,

  I just created a schedule using Primaver P6v7 and everything looks fine just as expected but the problem Im facing now is that my boss uses Primavera P6 v8.3.2 and something is not looking right when he imported the file into his system. The scehedule was resource ans cost loaded. When my boss imported the file, the dates looks fine but the "Budget At Completion" doesnt match the original schedule. Whats is going on, someone help?

Thanks
