## Problem

> ℹ️ Error log shows: “Multiple values found for lookup 'nnn' to entity 'Contact' on field 'Referencenumber'“

Applies to P360

## Solution

Two contacts with the same id (nnn) is defined in the archive system. One of them must be deleted. 

NOTE that one of the contacts might be disabled. -But due to a bug in P360 this is not suficcient. The contact MUST be completely removed

> ℹ️ There exists a duplicate contact in the archive system
