What limitations exist for SUM and AVERAGE in Group functions?

The correct answer highlights that the SUM and AVERAGE functions are designed to operate specifically on numeric data types. This limitation is crucial because these functions are intended to perform mathematical calculations, which do not apply to non-numeric types such as text or dates. In contexts where data aggregation is necessary, such as in financial reporting or data analysis within NetSuite, using SUM or AVERAGE on non-numeric data would not yield meaningful results.

Understanding this limitation is essential for anyone working with databases, as it defines the scope of analysis possible with these functions. For instance, attempting to calculate the sum of text entries or the average of date values would result in errors or invalid outputs, illustrating the importance of ensuring that data types are compatible with the chosen functions.

This specificity ensures that users apply these functions correctly and effectively while working with data sets, supporting accurate analysis and reporting.
