In the last scenario, Dynamically Expand Columns, I add a new column to the inner table with the content of the column of the outer table I want to keep. So I can use Table.Combine instead of Expand.
Hi.... One request. Suppose we complie a data in power Query & now want to make filter range in Excel so that I could see only specific period or number range... Like 645070 to 645090 or SEP to NOV
When you add values to the Table Object (like the Table.AddIndexColumn does in the video) the table is not the same as the source data. It allows you to perform operations on the grouped rows -> then expand them without any data type issues.
is there a way to show that the query created in power query hasn't been modified so that auditors can see that once the source file has been updated, the query will run in the same way ? i can't find anything; in Alteryx, you can see when the workflow was last modified but i don't know how to see this in power query so that's not good
@@BIGorilla hmmm, not sure they'll want to compare lines and lines of coding from one query to the next; some of my processes have way over 50 lines. I don't know why MS haven't thought of this as this is a basic requirement really; just like Alteryx offers; anyway, thanks for your help
@@pascaljoly5752 in all my years of working I’ve never heard of this requirement before. It sounds pretty niche to me. Power query started as basic data transformation tool in excel. Then later on it matured to power bi. And it grew. Alteryx is a different product, with licensing costs that are enormous. Not for the average self service employee. I think they cater a different profile user
How about that when it comes to Expand solution? Too simple? = Table.ExpandTableColumn(#"Grouped Rows", "Details", List.Difference(Table.ColumnNames(#"Grouped Rows"[Details]{0}), Table.ColumnNames(#"Grouped Rows")))
Hey mrBartus. That approach is very similar, with the difference being you used List.Difference, while I used List.RemoveItems. Other than that I showed it using variables, and you pasted it all together. Both methods work fine :)
