Hi,

I have to authenticate user by their roles, previously I used to keep formula in onstart it used to work fine, but since power apps included new feature (i.e startscreen), I am not able to use this formula neither in onstart nor in startscreen both ways it is showing error.

Thanks in advance

Hi @Hemasai1999 :

The point is that StartScreen is a data flow property that can't contain behavior functions.In addition, Global variables and collections, including those created in OnStart, are not available in StartScreen.

I think this link will help you a lot:

StartScreen property

You could try to set the app's StartScreen property to:

With( {varRole:LookUp(XXXXXXX)}, If( varRole.Role="LP", 'Lp screen', varRole.Role="Admin", 'Admin screen', varRole.Role="Trainer", 'Trainer Screen screen', varRole.Role="LC", 'LC screen', 'No Access screen' ) )

Best Regards,

Bof
