Identify duplicates

Hi kellyylx - Create a New Calculated Column: Add a DAX calculated column to your table to check whether any record for each contact name has last activity > 2 years ago set to TRUE.

replace with your model table name use below logic:

calculated column:

FlagHasTrue =
CALCULATE(
MAX('YourTableName'[last activity > 2 years ago]),
ALLEXCEPT('YourTableName', 'YourTableName'[contact name])
)

Now, create a table or matrix visual where you can apply a filter on this new FlagHasTrue column. Set the filter condition to show rows where FlagHasTrue = TRUE. This will retain all rows of the contact names that have at least one record with "last activity > 2 years ago" as TRUE.

Hope this helps.
