How can the system administrator address the issue of too many results in opportunity reports?

The option to use the show filter to filter report results and reduce records returned is a practical solution for managing the volume of results in opportunity reports. By applying specific criteria through filters, the system administrator can tailor the report to display only the relevant records based on defined parameters. This helps users focus on the data that is most pertinent to their analysis or decision-making process, ultimately improving efficiency when reviewing or utilizing that information.

In contrast, moving reports to personal or restricted folders may not effectively address the issue of excessive results in the reports themselves. While those options could control who has access to the reports, they do not change the number of records that are being reported on. Similarly, updating sharing rules may limit access to certain records but does not assist users looking for a refined view within the existing framework of a report. The focus in this context is on data management and filtering, making the use of filters the most logical and effective choice.
