I've recently worked on a data cleanse exercise and rather than use fields to capture additional information, I was advised to store the information on data cards. I have set these up as a custom object, however when creating a segment filter using one of the (data card) criteria, I noticed there were more data card records in Eloqua (meeting this criteria) than on the list I uploaded .
I think this is because I uploaded the list more than once and didn't select "update existing" on all of the occasions. I now want to delete the duplicates so the number of records match the number of submissions. Hoping to get some help on this asap. Many thanks
