To show the total number of Sales Orders created in the Results tab of a Transaction search in NetSuite, you should add "Field: Document Number" with "Summary Type: Count." This configuration counts each sales order, leveraging the unique document number assigned to each transaction as a basis for the count. By using the document number field in combination with the count summary type, the search will tally the total number of sales orders in the dataset, providing a straightforward metric for the volume of sales orders created. This is particularly useful for tracking sales activity, monitoring order volume over time, and assessing operational efficiency.References: NetSuite Help Center, Saved Searches Documentation.
