Sometimes, due to some reasons new customers are created which already exists or having the same details as per the old one to overcome this issue Business Central has a solution that we can merge details of the required one with the desired one and the best benefit of this is that the entries which has been done for the new one is also merged with desired one.

Here for instance, in our system new customer is created by user mistakenly which is having same details as the existing customer.
