How do I merge PivotTables with same identifier in the first column?

It looks like Jan, Feb and Mar are separate columns in your source data?

Simply put Jan, Feb and Mar in the Values section of one pivot table.

Please attach a sample workbook (not a picture or pasted copy). Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate. Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.

Click on GO ADVANCED and then scroll down to Manage Attachments to open the upload window.

You need to normalise (unpivot) your data first, then you can report on it in the way you want.

Use Power Query (Get & Transform Data) to transform your source data:

Close and load to data model, then insert a pivot table based on data model, with
Filters: Reporting, Group1, Group2
Columns: Month
Rows: Value
Values: Count of CR Nummer

See attached workbook, with pivot output in sheet "AFTER".
