Use cases
- Exclude all items with duplicate identifiers
- Exclude all but one item with duplicate identifiers. For example, keep the item with for example the lowest price
- Exclude the items with higher prices
Use the Deduplicate items action to manage duplicate items in your product data. For example, most channels do not accept reuse of GTIN codes for different items, because they are meant to be unique identifiers.
Exclude all items with duplicate identifiers
Choose the field to use for removing duplicate items. For example, you can exclude all items with duplicate values in the id field.
Applying this rule to this example data, both "Nike Air Max sneaker" and "Adidas Classic sneaker" are excluded because they have the same id.
| id | title |
| 123 | Nike Air Max sneaker |
| 123 | Adidas Classic sneaker |
| 654 | New Balance sneaker |
Exclude all but one item with duplicate identifiers
In some cases, you would rather keep one of the duplicate items. For example, when you know you want to advertise only one variant with the lowest price.
Exclude the items with the higher prices
The Round Design Tables are different sizes, but the same id. If you want to advertise with the lowest price only, you can use deduplicate items to exclude the items with the higher prices.
| id | title | price |
| 234 | The Round Design Table 100x100cm | 650.00 |
| 234 | The Round Design Table 120x120cm | 750.00 |
| 234 | The Round Design Table 140x140cm | 850.00 |
| 653 | The Square Design Table 50x50cm | 500.00 |
This means, after applying the deduplicate rule, the output data looks like the table below:
| id | title | price |
| 234 | The Round Design Table 100x100cm | 650.00 |
| 653 | The Square Design Table 50x50cm | 500.00 |
