Tutorial: Check field and system permissions in screen flows when using System Context using ExecuteSOQL

With the advent of System-context screen flows I can’t help but think of the famous phrase ‘With great power comes great responsibility’. When running screen flows in system context, you could inadvertently grant Read or Edit access to a critical system field to the wrong audience. Let’s say you wanted to do some cool stuff like in Jen Lee’s recent post about Community User Management, and you want to ensure the person running the flow has the ‘Manage External User’ permission. Her flow does this check using a custom permission, which is totally fine, this just checks the system permissions directly.

All of that is possible with some straightforward SOQL queries against the Permission Set Assignment object. You may or may not be aware, but the PermissionSet object actually contains Profile permissions as well so it’s a one-stop shop for getting Field and System permissions!

Run an action to check a field permission

The following example will run you through a VERY basic scenario where a Flow presents a screen to update a given field and the flow is running in System context – God mode.

  • We let the user pick an Account Rating in a basic Flow screen with a picklist radio button
  • We run the ExecuteSOQL action to check if the running user has ‘Edit’ permission for the Account Rating field.
  • For older versions of ExecuteSOQL that return an ’empty’ collection we assign the count of the results to a number field
  • We then do a decision to see if the number of permissions assigned to the user is > 0.
  • We then either show a screen that says you cant edit it or we move on with updating the field.
Flow Overview

Most of you can probably handle the beginning and end – so I’ll provide some more color on the middle part that does the permission checking.

  • You’ll want to construct your query using a Plain Text text template variable:

SELECT AssigneeId,PermissionSetId,Permissionset.Name,Permissionset.Profile.Name
FROM PermissionSetAssignment
WHERE Assignee.Id= ‘{!formulaRunningUserID}’
AND PermissionSetId in (Select ParentId from FieldPermissions where SobjectType = ‘Account’ and Field = ‘Account.Rating’ and PermissionsEdit = true)

*WARNING* If you make any edits to the text template variable, a Flow bug will revert the template back to rich text and it will break the action! Make sure you revert it to Plain Text after every edit.

  • Next up is to make the ExecuteSOQL action:
  • Here’s an example result from the action above that returns the permission granted by the System Admin profile when run as myself.
  • (For older versions of ExecuteSOQL only) You’ll then want to assign the results to a number since older versions of ExecuteSOQL return an empty collection if no results are found. Make sure you set the default value to 0 when making the variable.
  • Use an ISNULL check if you’re using the latest and greatest.
  • Create your decision and you’re done!

Checking multiple fields

You could of course extend this to multiple fields in one query by modifying the SOQL query, for example:

SELECT AssigneeId,PermissionSetId,Permissionset.Name,Permissionset.Profile.Name
FROM PermissionSetAssignment
WHERE Assignee.Id= ‘0051I000000UB4LQAW’
AND PermissionSetId in (Select ParentId from FieldPermissions where SobjectType = ‘Account’ and
Field in (‘Account.Rating’,’Account.Type’) and PermissionsEdit = true)

System permission checks

You can also check for specific system permissions! Let’s say you wanted a Flow embedded on the Case layout that manages the Contact’s community user record. The query below could be used to check if the user handling the case has permissions to manage the external user account:

SELECT AssigneeId,PermissionSetId,Permissionset.Name,Permissionset.Profile.Name
FROM PermissionSetAssignment
WHERE Assignee.Id= ‘{!formulaRunningUserId}’ AND PermissionSetId in (Select Id from PermissionSet where PermissionsManagePartners = true)

Get Record Type Info by Object – Flow Action

This action can be used to generate a list of record types for a specific object. This can be useful when you would like to present a record type selector to the user. Can be used as inputs to the QuickChoice managed package by setting Input Mode to “Dual String Collections”. Pass in one output collection for Labels and one for the underlying values

Inputs

AttributeTypeDescription
Object NameStringAPI name of the target object example “Task” or “MyObject__c”
ignoreMasterRecordTypeBooleanIf “on” then “Master” will not be added to the list of record types
onlyReturnActiveRecordTypesBooleanIf “on” then only active record types will be added to the list
onlyReturnRecordTypesAvailableToCurrentUserBooleanIf “on” then only record types available to the current user will be returned

Outputs

AttributeTypeDescription
errorsStringcaptures details of any error that occurred
recordTypeIdsStringIds of the records types.
recordTypeNamesStringNames of the record types.

Installation

Install this action as part of the QuickChoice managed package or as a standalone package.

How to create a Map collection in Flows by Narender Singh

Narender Singh form ForcePanda wrote a two blog series about using map collections in flows. The second blog makes good use of the new generic sObject support in flows coming in the Spring ’20 release

Navigate to a Record in View or Edit Mode at the end of a Flow

A common need in Flows is to be able to redirect the user to a new record that may have been created in the Flow. This new Lightning Flow Action can be used to redirect the user to the specified record in either View Mode or Edit Mode.

How to Build a Flow Action with Apex

The other day I built a flow action that generates random numbers. While doing it, I recorded the process, because we don’t have a lot of tutorial material on how you can turn a chunk of useful Apex code into a nice, declarative flow action.

Here it is.

For a general introduction to the invocable action interface, check this out.
