By default, what line does a transaction saved search default to?

The correct answer is related to the structure of transactions within NetSuite and how saved searches are typically configured by default.

In NetSuite, transactions such as sales orders, invoices, or purchase orders are organized into different levels. The "Main Line" refers to a single line item that represents the overall transaction, summarizing the key information about it without going into the details of individual line items.

When a saved search is created for transactions, it defaults to the "Main Line" to provide a high-level overview of the transaction details. This approach allows users to quickly access essential information without the need to sift through the specific line item details, making it efficient for report generation and analysis.

Moreover, the options that focus on line levels, header only, or sublist information would require additional configuration to access more granular details or specific categories of information. Thus, the default behavior prioritizes summarizing the transactions efficiently through the "Main Line," which is useful for most reporting needs.
