Hi

I referenced DataSet &

Tried Following

 

let
Source = Data1,
#"Added Custom" = Table.AddColumn(Source, "Index", each if [Location] = "US" then "" else 0/1),
#"Changed Type" = Table.TransformColumnTypes(#"Added Custom",{{"Index", type binary}}),
#"Removed Errors" = Table.RemoveRowsWithErrors(#"Changed Type", {"Index"}),
#"Removed Columns" = Table.RemoveColumns(#"Removed Errors",{"Index"})
in
#"Removed Columns"

 

Its Working for me.

Hi @yogeshmaney 

 

Not sure to clearly understand your question but I am thinking you could Reference an existing query and apply the desired filters.

 

Inside Power Query Editor, right-click a query in the Queries pane (left side) and click "Reference".

It will create a new query (new table) dependant on the first one. Then you apply your filters as desired.

 

Let us know if that works for you.

Thanks David. 

But referencing is Duplicating Data. I need to create a new Table by filtering rows.

Tried Table.RemoveRows but giving error

@yogeshmaney 

 

Can you provide some screenshots and examples of your current scenario and the desired output?

Here's the sample

I have

Sr ItemLocation
1AUS
2BUK
3CUS
4DFR
5EUS

 

I want, A table for US  location 

Sr ItemLocation
1AUS
3CUS
5EUS

 

 

@yogeshmaney , have you tried Table.SelectRows()?

 

= Table.SelectRows(
  #"Previous step",
   each [Location] = "US"
)

 

Let us know if that works for you

Great! Glad you found something that works for you @yogeshmaney 

 

I guess you could simplify that M code with:

let
Source = = Table.SelectRows(
   Data1,
   each [Location] = "US"
)
in Source

@David  That's Filtering Column. Data I am fetching is from Event Store. Each Referencing is around 750 MB . Need 20-25 such reference. And Making File heavy. Inside there are JSON blobs.

Deleting is the only option
