How to Opportunity saved search formula to show opportunities with only one line item

AI generated answer (using internal Slack threads):

To create a saved search for Opportunities that only have one line item, you can use the 'Summary' type of criteria in your saved search. Here are the steps: 1. Navigate to the 'Criteria' tab of your saved search. 2. Click on 'Summary' type. 3. Select 'Count' from the dropdown. 4. In the field, select 'Item' or 'Line ID' (select it from the dropdown). 5. Set the operator to 'equal to' and the value to '1'. This will filter the Opportunities that only have one line item. Please note that you may have to exclude tax/shipping/cogs/mainline. If you still see Opportunities with multiple line items, it might be because the search is splitting up the orders by line item. To avoid this, you can try using 'Group' instead of 'Count' in the summary type. Please note that this solution is based on the assumption that your line items are represented by the 'Item' or 'Line ID' field in your Opportunities. If this is not the case, you may need to adjust the field accordingly. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
