Reconciling A/R with GL

Does anyone have any tips in regards to reconciling the Receivables
Aging with GL?

We went live 10/1/07 and realized there were errors on the receivables
aging report. We reported those errors to Vantage and they eventually
fixed them.

Any tips would be greatly appreciated. We've been doing this for over
15 years in other software and not understanding why it's so hard in
Vantage. If we knew the correct way, it may not be so hard!!!!

Thanks,
