What is a key requirement for grouping reference fields in component worksheets effectively?

A key requirement for effectively grouping reference fields in component worksheets is that each reference can be uniquely identified. This principle ensures that when data is organized or aggregated, it is clear which specific record corresponds to each reference. A unique identifier prevents confusion and potential data integrity issues that could arise from having multiple records share the same reference.

When references are uniquely identifiable, it allows users to easily locate and interact with data specific to that reference during analysis or reporting. This is essential for maintaining clarity and accuracy, particularly in environments where precise data manipulation is crucial.

The other options do not have the same level of importance in the context of effectively grouping reference fields. For instance, sorting records alphabetically, while beneficial for organization, does not inherently support the grouping process. Similarly, the requirement for records to be sequentially numbered or for reference fields to contain only non-duplicated values does not address the primary need for unique identification necessary for effective data grouping.
