User not able get the value in reports After Upgrading to BO 3.1 to 4.0

Hi Experts,

We have upgraded the BO 3.1 to 4.0 and we are having 2 groups Developers and End Users.

Developers having full access and the end users having View on demand acces before upgrade in 3.1.

After upgradation for developers we dont have any problem but for end users when they refresh the report they are getting database error but for the same

users we tried in bw directley , working fine in BW.

Could any one please help.

Thanks,
