Expand columns with new columns

[Syndicate_Admin]

Good morning BI experts!

I have a question that has to be easy to resolve.

The database I start from is already established and I can't change it. They are the hours worked per project and represented in a matrix way.

I have created a very simple example, in which we are only going to play with two years (20 and 21) and with the names of projects (A,B,C,D,...)

I have 1 tab per year.

Table year 2021:

In power Query, in the step of expanding columns, these projects are successfully expanded, as this is the first time I expand them:

In the year 2022 and beyond, there will be projects that are closed and therefore there are no columns for them, and new projects will arise:

But these projects don't work out for me. If I go to the step of expanding columns, I see that they are not selected.

Therefore I select them and the data is updated correctly.

But I can't be every time there's a new project selecting all the projects.

Is there a way I won't be deselected for new projects?

Thanks a lot!

Greetings,

Javier

You can use Table.ColumnNames(#"Added Custom") to dynamically get the names of the column headers to expand in place of the hard coded values {"A", "B", ...}.  You may need to use one of the List Functions to get just a subset of those columns, if you see duplicates.
