XrmToolBox | gather multiple tools to ease the customization

I have no background in Microsoft Dynamics CRM and the company I'm at lost their one developer who was maintaining this system. There is a function app with some code I'm trying to understand. The intent of the code appears to be to determine the user who set a price discount to then either permit it or not. It gets the audit entities associated with the salesorder that contain a 115 in the CSV AttributeMask.

An unexpected error occurred:

System.Exception: Error while deserializing configuration file. Details: There is an error in XML document (13, 8). at McTools.Xrm.Connection.ConnectionManager.loadConnectio nslistO at McTools.Xrm.Connection.ConnectionManager..ctor0 at McTools.Xrm.Connection.ConnectionManager.< > c.<.cctor> b_ _70_00 at System.LazitCreateValue0 at System.Lazyl.lazylnitValueO at XrmToolBox.New.NewForm.ManageConnectionControl0 at XrmToolBox.New.NewForm..ctor(Stringl] args) at XrmToolBox.Program.Main(String0 args)

I need to add a new "auto-number" field to an entity in Dynamics365 CE.

Thanks to Jonas Rapp's excellent XrmToolbox "Auto Number Manager", adding the field and defining its look is a breeze.

My challenge is: I have 100'000+ existing rows in that entity - how can I update the existing rows with the correct auto-numbering values?

I have tried it - but even if I make the "auto-number" field "required", creating it doesn't fill the values for the existing rows. I would have hoped this would be done automagically - as with a "computed column" or a new "not null" column with a default value n SQL Server.

Any easy ways of doing this? Can I somehow updates those existing rows via a workflow, or via the REST API ?

I'm trying to get the list of records from a crm entity using c#. Trying to get the records with IDs present in another list.

Here is the query:

Seems like every other day XrmToolBox's Plugin Registration tool fails to connect. It's probably the most fickle tool I've ever used professionally (is this really the best tool for the job? yikes)

In years of working with it, I've not yet found a reliable way to get the tool to connect. Everything connects fine in the browser. But XrmToolBox randomly fails.

And I've never found or read online a reliable way to figure it out except restart your computer, throw salt over your shoulder, spin counter-clockwise once in your chair, try again later.

Anyone have a better way?
