How should you configure a report definition to display purchase requests for regional cost centers with each cost center appearing only once?

To display purchase requests for regional cost centers with each cost center appearing only once, configuring the report definition to group the results by cost center is the most effective approach. Grouping the results by cost center consolidates all the purchase requests associated with each specific cost center into a single entry for that cost center. This means that instead of displaying each individual purchase request separately, which could lead to redundancy and clutter, the report will summarize the requests, showing each cost center only once.

Grouping is essential in this scenario because it creates a structured view of the data, allowing for easier analysis and interpretation. By focusing on the cost center, stakeholders can see the overall purchase activity per cost center without being overwhelmed by duplicates or excess details, thereby achieving a clearer understanding of the purchase trends and needs for each regional cost center.

Sorting the results by request date or filtering by purchase amount would not achieve the goal of displaying each cost center uniquely, as those actions focus on the ordering of information or limiting the data shown rather than aggregating entries. Grouping by request type does not address the need to consolidate by cost center, making it less suitable for this requirement.
