Removing blank items from a lookup column

[Ian-S]

Hi,

I am looking for a bit of help.

I have a PowerApp choices column (EE) which is a lookup in SharePoint. It has lots of blank items I would like to remove.

The List is called DRS and the column is EE containing the items.

I have tried (and failed) to use the IsBlank ☹

I tried this in ‘Items’: Filter(‘DRS’, IsBlank(EE)=false) Any assistance would be appreciated.

Thank you.

You can do this by adding .Value to the EE column.  I believe the reason you original statement is failing is because EE still holds a record with Id and Value.  Even though those are blank the record still counts as not-blank. 

Filter(‘DRS’, IsBlank(EE.Value)=false)

Thank you for the reply and suggestion but that didn't work 😞 

When I click the box on the dropdown arrow, nothing happens at all. It doesn't even open.  No red error, just a line saying  "
Delegation warning. The "Filter" part of this formula might not work correctly on large data sets"

The SharePoint column is a single line text with a lookup to another list (that contains blanks).

Hi @Ian-S ,

Do you mean that:

EE is a lookup field in DRS list and you want to display this field without blank value?

If so, try to set the drop down's Items for EE:

Filter(
       Choices(DRS,EE),
       !IsBlank(Value)
)

Delegation warning:

Could you tell me how many record are in DRS list?

If it is less than 2000 records, you just need to change delegation limit to 2000.

This warning will not effect your app's performance.

Or else, it will be a little complex since Choices() function is not delegate.

Best regards,
