How to view which permissions a security role really has in Dynamics 365 for Finance and Operations

The key word in the title of this post is "really" - this isn't about how to look in the AOT or how to open the security forms in the browser - this is about how to check what an AOS is picking up as security permissions for a given role under the hood.

Why would I want to do that I hear you ask? It's useful for me when I'm developing new security elements - because the AOS doesn't see them until I do a full build and database synchronize(sometimes just a synch if everything is already built), and I can't always remember when I last did a build and database synchronize - so it gives me a simple way that I can check what the AOS actually see's for a security role. Also if you're troubleshooting something wrong with security in a deployment environment it gives a way to see what the AOS is seeing.

How can I do it?

Earlier, I created a new privilege, which granted a form control permission to a control called "GroupFinancialDimensionLine" on Forms\SalesTable, then I created a role extension on the Accounts Receivable Clerk role, and granted it my new privilege.

What I want to do now, is see if my AOS knows about it or not - or if I need to run a full build/synch.

Querying my AXDB, first I'm looking up the RecId for the role I modified, then I'm using that RecId to check what permissions are set for SalesTable for that Role - looking in the SecurityRoleRuntime table.


A couple of things to note:

- It's database synchronize that's populating SECURITYROLERUNTIME.
- AOS is using SECURITYROLERUNTIME as it's definition of the detail of each role - this is how it knows what to allow a user to see/do and what not to.
- AOS only reads from the table on startup**, and then it's cached.
- When you're deploying a package to an environment - no further action should be needed - the will be populated if package deployment completes successfully.

In my example, after a database synchronize, I can see my new permission is there, and then when I log in with a user with that permission it works:

**I said that an AOS only reads the table on startup - that's not strictly true, it just made a nicer bullet point. There is a cache synchronizing mechanism between AOS - so that if someone modifies a role/permission in the UI, the other AOSes will pick up the change by re-reading the table:

- Each running AOS has in it's memory a global user role version ID
- It's getting this from a special record in Tables\SysLastValue
- Periodically (every few minutes) it checks the SysLastValue record to see if the ID has changed - meaning has another AOS made a role change, and notified the others by incrementing the global user role version ID stored in this table.
- If it's changed it flushes it's cache and re-reads all the role information from SecurityRoleRuntime

It's a similar type of mechanism that we use for AOS to check their server configuration, batch configuration and EntireTable cache settings/values.
