On the one hand, I have the table with the sections of my matrix:

Then, for each line in that table, I have a measure that calculated the amount.

Once I have all the measurements, I make the matrix:

Measure "Apartado_ordinatto 3" is as follows:

Apartado_Ordinatto 3 = SWITCH([apartado_ped_selec3],
1,[Ped_En_El_Mes_Hasta_NACIONAL],
2,[Ped_En_El_Mes_Hasta_EXPORT],
3,[Ped_En_El_Mes_Hasta],
4,[Ped_Recibidos_el_NACIONAL],

It is a switch that binds the id to its respective measure to create the array. The problem is that in the matrix, in columns I put the column name of the table but as you can see, it is a title that should change according to the filter that is put in the date reclassification.

Also, if the title is "Orders in the month to DATE" it should be changed to Orders in the month to 13/10/2023 (this is an example.)

Sorry, I've already added the sample data before, I don't know what else data you need...

It would only take some measure to test it, but it can be anyone.

Ped_En_El_Mes_Hasta_NACIONAL = 1

In the end, it doesn't matter what the number is... All I want is the title that appears.

Here I leave a pbix

It would be about making the column headers that appear as Customer 1, Customer 10 pass them to Customer 10 and the date selected in the segmentations, in this case remaining, Customer 1 1/3/2023 and the other Customer 10 1/3/2023

The problem is that the date isn't a column in the table, it's a date selected from the slicer. In the first comment there is a screenshot where you can see it.

It won't let me put a measure as a column. Besides, I don't want a new hierarchy on top, I want a single header but one that is dynamic.

I would already have the table, what I don't understand is "all possible permutations...". Could you give me an example?

Yes, I've already proven that. I've created a custom column as you say, dates + client

But I can't find a way to create the personified column and grab the selected dates from the segmentation....

I'm sorry, I don't understand.

I have a separate table with the titles, so the next thing would be to create a measure but that captures the value of the segmentation, is that right?

If so, as I mentioned earlier, it doesn't work because it doesn't allow you to put that measurement as a column in an array.

I still can't find a solution... I don't know if you can help me with a small example of what you are talking about.

Thank you.
