unable to use PowerApps filter function on a SharePoint lookup column

What is the best way to filter a SHarePoint Lookup field in a PowerApps canvas app?

 

I have an "Asset" list with 2 fields.
"AssetName" column (Text Field)
"AssetType" column (Lookup "TypeOf" column from "Type" list)

 

"Type" list has 1 field
"TypeOf" column (Text Field)


Now I have a List called "Service" with 2 fields
"AType" field (Lookup "AssetType" column in "Asset" List)
"AName" field (Lookup "AssetName" column in "Asset" list - But filter based on selected AType column)


Now this is how I did it in PowerApps

 

"ATypeDropdown" dropdown field
item property is Choices(Asset.'AssetType')

 

"ANameDropdown" dropdown field
item property is Filter(asset.'AssetType'=ATypeDropdown.selected.value).'AssetName'
But this doesnt work for me, I get an invalid argument type error.

 

Any help would be appreciated.

Hi @pm13 ,

 

I think you need to achieve this using a standalone dropdown control(outside the edit form) and then use Patch to update the item. For the standalone "ANameDropdown" dropdown field, set the Item property to:

Filter(Asset,AssetType.Value=ATypeDropdown.Selected.Value).AssetName

Then to Patch this AName field, use a formula like below:

Patch(Service,Defaults(Service),
{AType:ATypeDropdown.Selected,
AName:
{ '@odata.type':"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference", Id:Filter(Asset,AssetName=ANameDropdown.Selected.Value).ID, Value:ANameDropdown.Selected.Value}
})

Mona
