Global Approver for multiple apps within the same org

[A_San]

We have few apps like "Training Request Form", "Merit Award Form" etc. For all these forms, the approvers are same. The back end of all these forms are SharePoint Lists. Is it possible to create a Global Variable for Approvers so that can be used everywhere instead of their email/user ids ?

Power apps has no capability to create a global variable across multiple apps.  The best workaround would be to create a SharePoint list where you can add all the approvers and then set the apps to use that list when assigning approvers.

Thank you @Pstork1 . So does that mean, the approver list from Sharepoint can be used in the power apps forms? Like some fields are visible only to approvers in the forms.

Since the list won't change frequently and will be used repeatedly in the app, I would add something to the OnStart of each app that reads the list and stores it in a local collection.  If you ever need to add or remove approvers just edit the list and the next time any of the apps are started they will get the fresh list.  

Not sure how you are doing the visibility of specific fields.  I'm assuming you are checking to see if the current user is in that list.  If so, then yes you could use it that way.  But I need to point out that that isn't security since it only applies to the Power App and users can still see all the fields if they go directly to the SharePoint list.  But the Approvers list would just be another data source/Collection that you can use in your app.
