I need to find, in B2C scenario, a solution where new users cannot create accounts
using duplicate address data.
( When new user tries to create a user with duplicate data the webshop page should show a message, telling certain duplication problems.)
I read that there is an add-on for Service Industries, which is free.
However I do not know how to find and install it.
I also read that it has a transaction code CRM_BUPA_DC for cleansing cases.
If anybody knows how to find the installation files and installation procedure, I will be very grateful.
