In the situation where your customer (the engineering company, or end user) provides you with a numbering scheme for your document register, why not let DocBoss do the hard part?
By simply identifying the make-up of the customers numbering scheme i.e. “<DocCode>-<Sequence #>-<Sheet#>”, DocBoss will assign numbers to your entire register.
Of course, we keep track of when you TELL someone about these numbers and then we lock them down for you.
But before that, make all the changes you want. No one’s watching.
