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 ?
