If you tick Record data that would be lost as a Note in the retained record the content of a data record that is partially overwritten will be copied to a note during the merge of the double data records so that you still have access to them afterwards.
Next, you select which data records should be merged after the duplicate check. The options are notes, opportunities, histories, activities, documents, secondary contacts and groups.
In the end you go on the symbol. You created a DUPE|IT schema! Continue reading in the chapter Run schema if you want to start it now.
