Is there a standard SAP way to check whether the customer database contains duplicate entries?
Customers has been created for a long time (9 years I guess) and we suspect that the database contains several double entries since there was no check at all. The total amount of customers is 230.000. The question is, is there a report with which we can analyse duplicate entries? I know there are some BADI 's which can be used for third party solutions to check addresses but I think it should be available in standard SAP too and hope it is.
At this moment the customer has version 4.6C but will move next year to th latest version of SAP.
Thanks in advance.
