CO-OM-CCA - Cost Center Reporting

Hi

When I run report S_ALR_87013612 Area Cost Centers where a cost center has been entered more than once in the selection parameters, the cost center figures are listed the same number of times resulting in incorrect totals. How can I make the report output a unique list of cost center values regardless of the number of times any number of cost centers have been added more than once in the selection parameters. Thanks
