How do I resolve "Duplicate line number (No) Line XXX is duplicated" for a Zuora Bill Run?

Overview

After processing a Bill Run an error occurs, on review of the Bill Run Error file, the error is "Duplicate line number (No) Line XXXXX is duplicated." (XXXXX is the line number as shown in column J LineNo in the file)

Environment

Zuora

Resolution

• Upgrade to the newest Zuora for Avalara AvaTax version to clear this issue:
  • What preparations are needed for the new Zuora integration?
• ​After the configuration for the Avalara Tax Engine is complete, reprocess the invoice in a new Bill Run

Note​: Each invoice must have a unique line number for each item, but with certain versions of the Zuora connector, duplicate line numbers are possible.
