Update blank/Null value to fields (Date, User, Choice field etc.) in SharePoint list / database

[Sanoj]

Scenario :  I have saved an item to the SharePoint list and later decided to remove data from some fields (Date field, User field etc).  Edit the item and delete the field value and Save it back to datasource (SharePoin list / SQL database)

Issue :  PowerApps does not update the field to empty / null value. The field value remains as such in list.

Solution : Enable the "Experimental features" as shown in below screenshot. This will resolve the issue and you will be able to update field value to null after that.

Hello,

I have changed the following in Card under Update..

"If(Value(DateValue7.SelectedDate ) = ""; "0" ;DateValue7.SelectedDate + Time(Value(HourValue7.Selected.Value); Value(MinuteValue7.Selected.Value); 0))"

Now an empty field is transferred to the database. I think this could also work for Sharepoint.

I did not find the experimental option under my settings.

Sorry for my English.

Greeting René
