[mssss]

Hello, I am useing cds and I would like to know how to filter my lookup columns.

I would like to filter like this.

Filter(table, IsBlank(MyLookUpColumn) )

but not working😥

Hi @mssss ,

You cannot filter directly on Lookup columns - try this

Filter(
   AddColumns(
      table, 
      "MyLU",
      MyLookUpColumn.Value
   ),
   MyLU = Blank()
)

Thank you for your help!

I've tried but Add Columns part did not work.😅

Can it be used to the gallery?

@mssss ,

I thought that was what you are using it for - also how did it not work (error/not result you expected).

Thank you for your help.

First I have try just "AddColumns" but I got a error message.

When I set a only this table name, error do not show.

Am I doing correct?

@mssss ,

You left off the Filter and the Blank test at the end - I tested this here and you also need IsBlank.

Be also aware this may not work properly on large data sets.

Filter(
   AddColumns(
      table, 
      "MyLU",
      customer.Value
   ),
   IsBlank(MyLU)
)

Also please have a read of my blog on data structures and ask whether you really need that lookup column.
