Clear SharePoint field data

I would like to clear field/column value on click of a button for a particular item. I have a SharePoint Person type field (AssignedTo). I have tried using Patch and Blank function but it is not clearing the value. Currently, the AssignedTo value is set to a single user. 


Patch(Bookings, First(Filter(TaskList, BrowseGallery1.Selected.ID = ID)),{


I have tried ClearCollection function and UpdateContext({ReservedBy:""}) but that didn't work as well.

Hi everyone,


After hours of reseraching I could not clear a date value on the SharePoint list using Powerapps. I got this to work by using flow. However, it's not what I wanted to use for something as simple as this, but it was a workaround for now incase anyone is looking for one.


Create new Instant Flow, initiated by PowerApps button.

Get Item, 'ask in powerapps' for the ID. In PowerApps on a button I did... On Select: FlowName.Run(ThisItem.ID)

See screenshot for steps in flow. In the date column, I went to the Expression tab, typed in null and clicked OK. Inserts a Null expression.

did you already try AssignedTo: NULL ?

I was dealing with a SharePoint list that had a Choice Column.  My column had three choices, "", "PASS", and "FAIL".  I struggled getting the SharePoint list to update when I was attempting to set the column to Blank().  However, once I started setting the column to "", all was well.
