Merge multiple rows with alternating null values in Power BI

Anonymous — Tue, 09 Jul 2024 16:23:14 GMT

Hello,

This is the data I have currently. I am trying to merge every 3 rows for each customer order. Because all cell values are the same for each order's aa to ee, I would like the data to be cleaned in a way that displays one order per row.

aa	bb	cc	dd	ee	2020	2021	2022
a1	b1	Customer 1	d1	e1	1	null	null
a1	b1	Customer 1	d1	e1	null	1	null
a1	b1	Customer 1	d1	e1	null	null	1
a2	b2	Customer 2	d2	e2	2	null	null
a2	b2	Customer 2	d2	e2	null	2	null
a2	b2	Customer 2	d2	e2	null	null	2
a3	b3	Customer 3	d3	e3	3	null	null
a3	b3	Customer 3	d3	e3	null	3	null
a3	b3	Customer 3	d3	e3	null	null	3
a4	b4	Customer 4	d4	e4	4	null	null
a4	b4	Customer 4	d4	e4	null	4	null
a4	b4	Customer 4	d4	e4	null	null	4

This is the output I'm looking for:

aa	bb	cc	dd	ee	2020	2021	2022
a1	b1	Customer 1	d1	e1	1	1	1
a2	b2	Customer 2	d2	e2	2	2	2
a3	b3	Customer 3	d3	e3	3	3	3
a4	b4	Customer 4	d4	e4	4	4	4

How can I do this? Really appreciate your help!

Hi Anonymous ,

You can use the Group By functionality. You can find this either on the transform tab of Power Query, or right click on a column header and select 'Group By' from the list.

You will then need to select 'Advanced' and use your aa to ee columns as the groupings, and create aggregations for your years columns (I think SUM operation is appropriate for your use case). For example:

Hope this helps!

Hi Anonymous ,

Your solution is great, BITomS . Here I have another idea in mind, and I would like to share it for reference.

You can create a new table and use the DAX code as follows:

CalculatedTable = SUMMARIZE( OriginalTable, OriginalTable[cc], "aa", MAX(OriginalTable[aa]), "bb", MAX(OriginalTable[bb]), "dd", MAX(OriginalTable[dd]), "ee", MAX(OriginalTable[ee]), "2020", MAX(OriginalTable[2020]), "2021", MAX(OriginalTable[2021]), "2022", MAX(OriginalTable[2022]) )

A new table CalculatedTable is created, and the result is as follows:
