title: Power BI - How to display only the values which appear more than once in a column
body: <p>I have a table with multiple columns. One of these is 'EAN'. In this column there are supposed to be unique values. Unfortunatly this is not the case. Now I want to find all the values that appear more then once.</p>
  <p>I tried the FILTER, EARLIER, COUNTROWS. Nothing gives the output I'm looking for.</p>
  <p>Example:<br />
  Art A - 111<br />
  Art B - 123<br />
  Art C - 222<br />
  Art D - 222<br />
  Art E - 456<br />
  What I expect as output is just a table, column or chart where '222' appears.</p>
