Patch SharePoint person field to blank

Hi all,

 

Does anyone know please how to patch a SharePoint person field to blank?

I have the "Formula-level error management" experimental feature turned on.

The person field is single-select only.

I can successfully patch date and choice values to blank, but struggling with the person field.

I've searched this community and this is what I've tried:

Attempt 1:

 

Patch(
    'Business plan log',
    varRecord,
    {
        'Director name':
        {
            '@odata.type':"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedUser",
            Claims:Blank(),
            Department:Blank(),
            DisplayName:Blank(),
            Email:Blank(),
            JobTitle:Blank(),
            Picture:Blank()
        }
    }
)
);

 

 

Attempt 2:

 

Patch(
    'Business plan log',
    varRecord,
    {
        'Director name':
        {
            Claims:Blank(),
            Department:Blank(),
            DisplayName:Blank(),
            Email:Blank(),
            JobTitle:Blank(),
            Picture:Blank()
        }
    }
)
);

 

 

Attempt 3:

 

Set(
    varBlankPerson,
    {
        Claims: Blank(),
        Department: Blank(),
        DisplayName: Blank(),
        Email: Blank(),
        JobTitle: Blank(),
        Picture: Blank()
    }
);


Patch(
    'Business plan log',
    varRecord,
    {
        'Director name': varBlankPerson
    }
)
);

 

Attempt 4:

The above attempts with "" instead of Blank().

 

Any advice would be greatly appreciated, thanks!

For this to work you need to do two things.

1) For some reason the following code only works if you turn on Custom Errors under experimental features in Settings.

2) Once that is turned on you will be able to patch the person column with Blank().

Patch(
    'Business plan log',
    varRecord,
    {
        'Director name': Blank()
    }
)

The variable will need to be a record.  I tested it using a Context variable

UpdateContext({varAssignedTo: Blank()});
UpdateContext({varAssignedTo:{'@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedUser",
Department: "",
Claims: "i:0#.f|membership|" & cmbAssignedTo.Selected.Mail,
DisplayName: cmbAssignedTo.Selected.DisplayName,
Email: cmbAssignedTo.Selected.Mail,
JobTitle: "",
Picture: ""}});

 and then a Patch like this

Patch(
    AssignedToDataSource, Defaults(AssignedTo),{
         Title: <<Required Value>>, 
         AssignedTo: varAssignedTo}
)

Thank you, thank you, thank you.

I already had the setting turned on, but this way of patching Blank() against the field worked perfectly. I appreciate your quick and thorough response.

Patch(
    'Business plan log',
    varRecord,
    {
        'Director name':
        {
            Claims:Blank(),
            Department:Blank(),
            DisplayName:Blank(),
            Email:Blank(),
            JobTitle:Blank(),
            Picture:Blank()
        }
    }
)
);

 

The above approach works when the Person or Group field accepts Multiple Users.

It took me a few seconds (minutes...) to realize you were patching just the record not the individual attributes of the person field...I blame it on the Mondays! Thanks for this - very helpful!

i have 4 person field, which may or may not have data, i have tried all kind of methods none of them is working so far. if any of the combo box is empty then it throws the error.

    ),

     // else, go to success screen

    Navigate(Home);

   

)

 

Any idea for a fix 

 

how do you actuallly patch it. I mean where do you put this command

@Pstork1 Is there anyway to do this conditionally within the same Patch?

 

I have a 2 Person fields that will sometimes have a value and sometimes will not.  They are part of a large Patch Statement.  I would hate to have to duplicate that Patch Statement 3 times to manage if the fields are blank or not.  However, I haven't found anywhere that says putting an embedded If statement inside a Patch is possible.

 

As always your help is greatly appreciated!

 

Thanks!
