At Emdi we can fix a database when it has multiple duplicate entries in documents, customers and items.
In the clientele there are 2 ways, one is when we have a small number of duplicate entries and the other when we have a large number of duplicate entries.
select with Control + click the registrations that are the same, right click and I choose customer / supplier integration.
Priority is always given to the customer we select by right-clicking, so a record is created with the data of the selected customer and merges all the documents with him.
Consolidated customers become inactive.
