The number of registered business relations can grow rapidly, especially if many users are creating new business relations, entire lists of potential sales leads are purchased and imported, or the Sales & Marketing module has been in use for a significant length of time.

With a large number of business relations, it can be hard to make certain that they are all unique. You can check the existing business relations for duplicates or you can enable a duplication check when you create new business relations.

There are two separate procedures to check for duplicate business relations:

• Duplication check of existing business relations.
  
• Duplication check when new business relations are created.
  

Note
Define which method the duplication check uses in the Duplicate method field in the Parameters form. Checking for duplicate business relations in a large database will lead to a noticeable drop in working performance.
