Patch Name from Dropdown

Posted on by GAM1741

Hello all,

I'm new here and new to Power Apps and need some help please. I've searched the forms but haven't been able to find the fix yet...

Configuration: Select a record from the main screen; using "Collect" to save the record -> Navigate sends user to Action Screen -> User selects a name from the dropdown (from "Profile" list) -> User clicks a button to update the name in the "Main Data" list to the name selected in the dropdown. I'm using a separate "Profile" list due to my main data list being > 30k records.

Dropdown (working correctly): Distinct(Sort('Profiles',Name.DisplayName,Ascending),Name.DisplayName)

Update Button (Not working): ForAll(Collect_List1,Patch('Main Data',ThisRecord,{'Assigned To': Dropdown1.Selected.Result}))

Error: The type of this argument 'Assigned To' does not match the expected type 'Record'. Found type 'Text'.

Welcome to the forum and to PowerApps!!

First thing to understand... your formula has the ForAll backward. You are trying to use it like a ForLoop in some development language - which PowerApps is not. ForAll is a function that returns a table of records based on your iteration table and record schema.

It is more efficient to use the function as intended and will provide better performance, especially with a Patch function!!

Your issue is that you are trying to set a User column with text. You need to provide a full SharePoint user record (I assume you are using SharePoint).

However, you will need more than just a name. You will need the email of the user. Does your Profiles list have emails as well?

Keep in mind that SelectedText is a deprecated property!

Hi Randy,
Correct, I am using SharePoint. My Profile list requires users to select their name/email from the company directory but it doesn't have a separate column for the email specifically; only a column for the display name. The Main Data list Assign To column is also populated with the display name from the company directory.

I'll need to research the "ForAll" formula being backwards. I pulled this from a different forum and did get it to work with a combo box, but not with a dropdown.

First, ForAll can be "forced" to work kind of like a For Loop, but that is not what it was designed for and forcing it to do something is was not made for causes a nightmare for performance in your app.

Next, if Assigned To is a Person Column in your list, then again, you need to provide a SharePoint user record for it.

I will assume that it is a Person Column and that you only have a display name to work from (as supplied from the Profiles list).

Therefore, your formula would be:

With({_userRecord: With(First(Office365Users.SearchUserV2({searchTerm: Dropdown1.Selected.Result, top:1}).value), {Claims:"i:0#.f|membership|" & Lower(Mail), Department:"", DisplayName: DisplayName, Email: Mail, JobTitle: "", Picture: "" } ) }, Patch('Main Data', ForAll(Collect_List1, {ID: ID, 'Assigned To': _userRecord } ) ) )

In the above, the Office365Users connector is used to lookup the Office 365 user record of the person selected in the dropdown.

That information is then used to build a SharePoint user record.

And finally, that is patched to all the records in the table (created by ForAll) to change the Assigned To column.

I added the Outlook365 connector and formula exactly as written but it's returning the error "SearchUserV2 is an unknown or unsupported function in namespace 'Office365Users'"

Check your spelling perhaps?? SearchUserV2 is an absolutely valid action on the Office365Users connector.
