Help creating a table based on another one (only distinct value)

[MaxItaly]

Hello everyone,

I'm having some problems trying to create a table.

Let's say I have a table named "Table1", that has "Client", "Quantity".

I may have more rows for the same "Client" with different "Quantity", for example:

Client             Quantity

A                          5

A                          8

B                          3

What I'd like to do is to create another table with only a distinct value for client and for "Quantity" the sum of the related quantity.

Client            Quantity

A                         13

B                           3

I guess I may create the quantity via a SUMX(RELATEDTABLE('Table1'); 'Table1'[Quantity]), but what I'm not sure how to do is to create another  table that has the distinct value of the client.

Many thanks to anyone who may help me!

(P.S.: I have noticed that "Remove duplicates" removes ALL the rows of a duplicated value. So, if I applied that, it would remove all rows about "Client" A, right?)

Hi @MaxItaly,

You need to create a new table with the following sintax:

Table2 = SUMMARIZE(Table1,Table1[Client],"Quantit"y, SUM(Table1[Quantity]))

You can also duplicate the table on the query editor and choose transform make a group by client and sum the quantity.

Woah: you opened me a new world!
I was not aware of this.

I am still figuring out where to write that syntax, but I managed, in the meanwhile, to do it thanks to the graphic commands.

Many thanks!

But just be aware that if you just want to summarize your table you don't need to do an additional table, you can use measures and visuals to give that result and only have 1 single table.

I know it, but way too often the tables are not optimized for Business Intelligence operations   😞

No problem, you should use the Query to optimize your data and then use the measures to make your visuals. But this is just a good practice, because duplicating tables will have an impact on your analisys but also on size of files, dependency and overall performance.
