Hi,
I don't know if you faced the same problem but from time when I moved to SAP BO 4.0 from 3.1 every time when I install new ServicePack some old reports aren't refresh or refresh with missing values. Of course every time I create incident in SAP and every time got information that in higher SP this problem is resolved and it is but every new SP destroy something in other reports and it's frustraitng
Do you have the same problem ?
