HI everyone. I'm trying to capture some details of first time users, I'm using the following code:

// Store details for First Time User
If(
    IsBlank(LookUp(AppUsers,'User Email' = User().Email).'User Email'),
    Patch(AppUsers, Defaults(AppUsers), {'User Name': User().FullName, 'User Email': User().Email, Office365ID:User().EntraObjectId})
);
If(
    IsBlank(LookUp('Leave Allowances', 'User Email' = User().Email).'User Email'),
    Patch('Leave Allowances', Defaults('Leave Allowances'), {'User Email': User().Email, Office365ID: User().EntraObjectId}),
    Patch(LookUp('Leave Allowances', 'User Email' = User().Email), {'User Email': User().Email, Office365ID: User().EntraObjectId})
);

The AppUsers table gets updated fine, no problem there. The Leave Allowances table doesn't update the way I would like it, it adds user email and ID to a new record rather than updating an existing record. Any help as to why this is?

Thanks

Hi @WayneSS,

Assuming you are using SharePoint here, try this - it should update any existing record, or write a new one if none exists.
With( { _User: LookUp( 'Leave Allowances', 'User Email' = User().Email ) }, Patch( 'Leave Allowances', { ID: _User.ID, 'User Email': User().Email, Office365ID: User().EntraObjectId } ) )

Thanks @WarrenBelz but unfortunately that also keeps adding a new record and doesn't update the existing one.

@WayneSS

Hello, have you tried using the update Patch in this format?

Patch( 'Leave Allowances', LookUp('Leave Allowances', 'User Email' = User().Email), { 'User Email': User().Email, Office365ID: User().EntraObjectId } )

I hope this helps!

Hi @WayneSS,
Firstly, do you want to also create new records if none exist (this is what I initially assumed). If so you can go the "very long" way as below (probably a bit of overkill involved here), but I use that syntax regularly on Prod Apps and it works as expected
With( { _ID: LookUp( 'Leave Allowances', 'User Email' = User().Email ).ID }, Patch( 'Leave Allowances', If( IsBlank(_ID), Defaults('Leave Allowances'), LookUp( 'Leave Allowances', ID = _ID ), { 'User Email': User().Email, Office365ID: User().EntraObjectId } ) ) )

If you simply want to update existing records which will always be there
Patch( 'Leave Allowances', LookUp( 'Leave Allowances', 'User Email' = User().Email ), {Office365ID: User().EntraObjectId} )
Note - why bother with 'User Mail' as it is already the correct value.
