Display of all sales group in standard report MCSI

Dear Gurus,

In standard report MCSI, i have one problem.

My sales team wants all sales group should be display in MCSI even though particular sales group does not have any sales order/incoming returns/ sales/credit memos.All sales group should be display in list either with value or zero balance.

Right now system is showing list of sales group which have some balance in either of above field.

what adjustment i have to do to bring all sales group in this report.

please suggest me.

Thanks in advance.

Parag.
