What feature must a report have to prevent displaying the same cost center multiple times?

To prevent displaying the same cost center multiple times in a report, the feature of grouping results by cost center is essential. When results are grouped, all similar entries related to a specific cost center are combined into a single entry in the report. This means that rather than seeing each instance of a cost center listed separately, the report will show it just once, often accompanied by a summary of relevant information, such as totals or averages.

Grouping helps streamline data presentation, making it easier for users to analyze and interpret the information. It is particularly valuable in reports where multiple transactions or entries are associated with the same category—in this case, cost centers. By applying this feature, the report effectively aggregates data points, allowing for clearer insights without redundancy.

In contrast, options such as filtering or sorting may change which data points are visible or their order but will not inherently prevent the repeating of cost center entries. A column identifying unique cost centers alone would not ensure that duplicates are removed from the display but rather indicate their presence as distinct entries. Therefore, grouping results is the most effective way to achieve a concise and clear report on cost centers.
