Possible Symptoms of Duplicate Records
The following symptoms probably mean you have duplicate records:
The original versioned object definitions are not updated.
New object definitions with the imported object identifier are created and have a long name made up of the product name and row ID.
The quote and order transaction data refer to outdated product definition.
If you customize these products in a quote or order record, the quote uses the outdated definitions instead of the updated product definitions that you imported.
Duplicate product, attribute and class records are in the target environment.
