Update different field in same record (switch)

[amcfar1]

Hi all, 
Apologies in advance if this is confusing. I'm newer to apps, and from my Flow experience I know I'd use a condition or switch for what I'm trying to accomplish, just not sure how to translate that in the app.

Scenario is paperwork approvals. I've got an "approver decision" ,"submitter status", and "approver status" choice columns in SharePoint. The status columns are view only, while the decision column is actual input. The status columns are viewable in the form and a gallery.

Approver Decision Column	Submitter Status Column	Approver Status Column
Under Review	Submitted	New
Action Required	Under Review	Under Review
Complete	Action Required	Action Required
	Complete	Updated
		Complete

When "action required" is the decision, the submitter makes edits to their document, and then uses a toggle in the app to indicate it's been complete, then presses a save button. I'd like to be able to have the "approver status" column reflect "updated", put the submitter status back to "under review". This could go back and forth until the edits are satisfactory.

How do I write a switch statement for these scenarios to change all the statuses and patch them back to SharePoint? Is this possible? 

Thanks in advance!

You can use a Switch statement in the OnSelect of that button to do one of several patches. Something like this:

With({ aLookup: LookUp()}, ​// a lookup that pulls up the current record you are handling
    Switch(aLookup.'Approver Decision',
        "Under Review",
            Patch(mySPList, aLookup, {}), ​// Update records as necessary in braces
        "Action Required",
            Patch(mySpList, aLookup, {'Approver Status': "Updated", 'Submitter Status': "Under Review"},
        // Add a no-match behavior here
    )
)

Make sense? The key is getting the With() statement to refer to the record you are currently working on.
