Alert

There was an error when modifying a Customers list, element "80008001-1473794522". QuickBooks error message: Cannot merge list elements.

Cause

This alert is typically caused when QuickBooks does not accept a change made to the customer. This is usually a change made to the display name, but can also be a mismatch of address, first and last name fields, or primary contact info.

Resolution

Find the Duplicate record(s) in FieldEdge and change one of the names in the display name field to differentiate between the records.

Retry the alert and post to QuickBooks. Make inactive, if the record is no longer needed.
