Datasource for Powerplay transformer?

[mu_ravi]

We have to create a cube in powerplay transformer.
So to create a cube we need datasource.I will finally publish this cube as package to cognos connection to use for our reports & dashboards.So my question is should we use direct package from Framework manager as a datasource forcube or how about the IQD process, i mean creating IQD's and using it forPowerplay transformer. Whih way is better , perfomnce wise and all otherways.?
Please help.

Thanks in advance.

I usually use reports as the datasource.  That way if I need to make a small change, I just change the report and don't need to change the entire package.
