Resolve duplicate data that you identify
During your analysis, you might identify that some of the data you are working with represents the same information and you need to decide how to resolve the duplication. For example, you find that two entities are aliases for the same person and you do not want them both to appear on your chart.
Merging is one way to resolve duplication that is not automatically dealt with. To help you, Analyst's Notebook provides tools that manually merge entities, multiple links, and combine attribute classes. These tools are located in Merge and Combine on the Analyze tab.
