3810812 - Duplicate entry or MG172 error when migrating Product Tax Classifications with multiple Tax Categories per country in Migration Cockpit

When migrating products using the Migrate Your Data – Migration Cockpit app with the Product migration object (staging tables), one or both of the following errors occur during Simulate for departure countries that require more than one tax category (for example France and Italy):

• Duplicate error

  1. Multiple rows are maintained in the Tax Classification sheet for the same country (for example one row per tax category: 2 rows for France, 3 rows for Italy).
  2. Simulate raises a duplicate entry error for the affected countries (FR, IT, etc.).

• MG172 error

  1. After removing the rows flagged as duplicates, only one row per country is kept with Tax Category 1 filled.
  2. Simulate fails with error MG172 – "You have not fully maintained the tax classifications"

Both errors stem from the same root cause when the Tax Classification sheet is not filled correctly. Neither the fully maintained variant (per UI requirements) nor the reduced variant (per Cockpit validation) migrates successfully.
