Data Loading Fine in Power Query but not Loading in Power BI

[WALEED]

I'm stuck at the "Apply query changes" dialog in Power BI after closing Power Query.

It's odd because T01 loads fine and displays all intended results in Power Query.

Here's the code from Advanced Editor: (Works fine in Power Query!)

let
    FilterSource = Table.SelectRows(CLKZ, each ([Key UID] = 287791)),
    FilterClass = Table.SelectRows(FilterSource, each ([OBJECT RELATION] = "TableTemToClass")),
    FilterColumn = Table.SelectRows(FilterSource, each ([OBJECT RELATION] = "TableTemToColumn")),
    Rows = Table.SelectRows(DATA, each List.Contains(FilterClass[OBJECT NAME],[CLASS NAME])),
    Columns = Table.SelectColumns(Rows, FilterColumn[OBJECT NAME])
in
    Columns

If I remove this line, the query manages to apply in Power BI

    Rows = Table.SelectRows(DATA, each List.Contains(FilterClass[OBJECT NAME],[CLASS NAME])),

I'd change Columns to this when making the change above

    Columns = Table.SelectColumns(DATA, FilterColumn[OBJECT NAME])

Some Context:

DATA = A table with roughly 200 columns and 200,000 rows.

CLKZ = A table with a set of relations that define sub-tables "T01, T02, T03, etc...)

T01 = a table extracted from DATA with certain columns and certain rows.

Both DATA and CLKZ are CSV files inside ZIP files in a Sharepoint folder. Both are loaded without trouble into Power Query as well as Power BI.

Perhaps it's a bug with a workaround? Perhaps there's a better way of doing this altogether?

@WALEED,

Please uncheck the following options in your Power BI Desktop file and then check if you can apply query change.

Hi @v-yuezhe-msft,

Thanks for the quick response. Gave it a go but unfortunately, I'm stuck at the same loading dialog.

@WALEED,

Is there any possibility that you can share us the data source? I will test it in my Power BI Desktop.

I'm afraid I can't because the data belongs to a company. I've had partial success by adding a column (TRUE/FALSE) to mark the rows wanted in Power Query (rather than filtering them out) so that I can filter based on this column in Power BI.

I am having the same problem.  Any update on this?

The complexity of queries and size of data cause exponential problems in Power BI. In this case, I ended up writing my own app to transform the data.

Sorry, I know this isn't the answer you're after.

Hi, 

I've got the same issue here : all the lines loaded in Power Query, only half in Power BI Desktop. I unchecked the boxes as recommended, didn't do anything. I deleted and recreated the query, didn't change anything neither. Does someone have an idea ? Is there maybe some cache files for  Power BI Desktop that the software is using instead of the feshest one ?
