consolidated business area

Hi SAP Gurus

In SAP ECC 6.0 we are using business area concept and Generating financial statement reports business area wise. Now we want to group certain business area under some group and for that “Consolidation of business area” functionality is given, we have grouped them , But no standard reports are available wherein we can enter the field consolidates business area as input field.

Please let me know that is there any more activation or further configuration required for getting consolidated business area reports

What is the procedure to activate consolidate business area in ECC 6.0, so that we will be able to see consolidation business area as input field for future reports.
