Using Infoobject for reporting directly or not?

Hi folks,

We have an infoboject in our BW system with about 2million records and this is expected to grow by 10% every year. There is a reporting requirement to measure compliance using 2 custom date fields from this infoobject. What is the best way to model this?

1. Use infoobject straight away in the multiprovider.

2. Load data from infoobject directly to a cube where compliance measurement is calculated within the transformation.

3. Load data from infoobject to DSO to cube where compliance measure can be measured in one of the tranformation; And use cube for summary reporting only and use DSO or infoobject for detail report.

Thanks for sharing your thoughts on the best approach.
