In a NetSuite Transaction search, the "Main Line" filter is a boolean criterion used to differentiate between the transaction's header information and its line-item details. By setting the "Main Line" filter to "yes," the search is instructed to return only the single, primary row for each transaction. This row contains the header-level data, such as the customer, date, and memo, while excluding all sublist lines like individual items, expenses, or tax details. This is the standard method for creating summary-level transaction reports.

B. This filters for transactions containing a specific item but returns all lines of those transactions, not just the main line.

C. This filters transactions by the entity name on the main line but does not restrict the output to show only that line.

D. This is the default behavior, which returns all lines (both main and sublist lines) for any matching transaction.
