Why would the basic opportunity search suddenly show multiple duplicates of the same opp (4-5 rows per opp)? This isn’t a custom transaction search with mainline omitted or anything.

Normally this happens to me when MainLine isn't set to TRUE, or I have results of joined fields that cause more results. I would start by making a copy and then start removing some results to see which one is causing it.

Think you’re right. Thanks.
