How to show data when only one column data changes?

[ianwuk]

I have data that looks like this:

License               ID         Date

12334                 123      7/7/17

45434                 456      6/7/17

67834                 123      5/7/17

As you can see, the same license key has two different ID numbers on two different dates (in UK format).

How can I show only those ones in a report? So only when the same license has one or more different ID?

Thanks.

You may need to create a copy of your data first, but does this help?  Once you 'Count' your grouped data, sort on that Counted valued >= 2 in a filter...

Thanks for this fhill!

I will give it a try next week and update here if I have any more questions.

Hi @ianwuk

Please add the following calculated column to your table (and adjust the name of the table to yours)

License Duplicates = CALCULATE(
                            DISTINCTCOUNT('Table1'[License]),
                            FILTER(
                                ALL('Table1'),
                                'Table1'[ID] = EARLIER(Table1[ID])
                                )
                               )

This will return a number that indicates how many other distinct licenses share the same ID which you can use in a filter.

Hello @Phil_Seamark, I tried what you suggested but I cannot get it to work.  I think I am doing it wrong.

Here is a better example of what I want to do.

How can I filter it so that only license keys in the licensekey column that are highlighted above appear because the license key is duplicate?

Many thanks.

When you first import you data into PowerBI, choose EDIT instead of OK.  Or you can hit 'Edit Queries' from the Home Tab.  This takes you into the Query Editor.  From here, highlight your LicenseKey column, and choose 'Keep Rows' 'Keep Duplicates' from the ribon.  This will only keep rows with duplicate values.  Just make sure LicenseKey is clicked and highlighted first.

Thank you so much @fhill!  That seems to have done the trick.  As you can tell, I am new to Power Bi.  As a separate question, do you know of any good Power Bi books I can read to learn more about how to use this program?
