How to add a customer ID?
I would like to add a ongoing customer number to each of my (and new) custumers. I tried to add a seqence in settings -> Sequence & Identifiers but i can't seem to add it to the customer account.
For example Customer John has customer ID 123. Customer Chris had customer ID 124 and so on.
I read something about adding a new .xml file but I don't know how to do this.
If this Question is allready asked i woul like to know where I can find the Question and the anwser.
