Final answer:
In the context of report design, the Design tab is where report grouping is defined, allowing for structured and coherent presentation of data.
Step-by-step explanation:
When working with a Report Designer to organize the structure of a report, one of the essential tasks is defining how the data within the report will be grouped.
Grouping data can help in creating a more organized and understandable report structure, which can be crucial in communicating the report's findings effectively.
To define the report grouping, you should use the Design tab in the Report Designer interface.
This tab allows you to specify how the data should be grouped together based on certain criteria, such as categories, dates, or any relevant grouping attribute within your dataset.
