In recent months, we have experienced enormous growth in the number of product and price changes that we process on a daily basis. To give you an idea, we currently process > 7.5 MIO products > 70 MIO prices per day between 23:00 and 08:00 and this number is still growing. We have therefore decided to re-develop the Product Exchange service towards the Product Data Store (import) so that we become more scalable to handle the future workload. There is also a user story in the product backlog to adjust the brands and product group matching so that they can be used in the suspecting algorithms you devised. Our development resources are limited and we expect to be working on this for the rest of the year and would like to work with you again in 2022.
Introduction
The current way of indexing the products has its limitations., sometimes wrong products are linked to a Product Data Index product, resulting in an inability to find the right products.
...
Another idea is to use the database with 2.5 MIO products with the manual knowledge of classification inside, to extract that knowledge with machine learning so not the user has to decide for on a classification mapping, but the machine does.
The idea
The idea, in general, is to identify suspects by comparing GTIN's, brands and manufacturer part numbers from the linked supplier items with each other.
The suspects will be displayed in the portal to the suppliers for their own products, the portal will also show the products that failed processing and not available in the Product Data Store. They can either correct their internal product data, so with the next processing, it will be correct, or mark the product to be correct. In that case, another supplier has probably to correct the product data.

The special interest group is open for registration.
Sign In!
We are looking for you to join a (or several is also possible 😊) customer panel. Registration for the customer panels is open till Friday 22 January.
Also, for the buyers, a portal will be available to display the suspects. And on top of that, the suspect flag will be available in the product data output and in the real-time Product Now.
Please find below a table for illustration with the processing errors and suspects, next to that is the user stories describing the suspect identification, supplier and buyer portal.

User stories
Suspect identification
As a Product Exchange user
I want matched products to be compared and suspects are identified
So that the buyers don’t get different products in their search results
Acceptance criteria:
- Compare matched products which each other and flag as suspect:
- when the GTIN differs between the sellers
- Multiple GTIN’s on PDI level can exist (different story)
- when the brands between the sellers differ
- when the MFPR between the sellers differs
- Check on GTIN
- Check on brand
- Check on MFPR
Background:
Products are matched on GTIN or MFPR and brand. When the GTIN or MFPR is invalid, this can result in different products for one GTIN or MFPR. These can be identified as suspects by comparing prices and brands.
Supplier dashboard
As a Product Exchange seller
I would like to, in case of suspects and errors as described in user story 1 and user story 3, be notified by mail and in the portal
So that we can monitor our product data quality and integrity to improve the searchability of our products
Acceptance criteria:
- Only the own products of the seller should be visible
- Email:
- How many errors/suspects per flag-type
- Date - time stamp of oldest error and flag
- Number of new flagged or error products
- Send once a day
- With a link to the dashboard
- Dashboard:
- Filter on headers
- Sort on headers
- Show all items with error or suspect-type
- Show the number of days/date
- Headers of the columns: SKU/MFPR/GTIN/Brand/Upload date/reason of error or suspicion/Flagged by (system, user)
- Export to Excel with the current selection (filtered output)
- Unflag products because the product data is right, multi-select if the filter is used
- Additional user role required
- Product exchange processing:
- Flag’s remain, unless the suspicion has been resolved in either the data or unflagged in the portal
- The flag will not return if the product is unflagged and the data is unchanged
- Unflagging:
- Multiple brands can be the same
- Products can have multiple GTIN’s
- Other
- If more sellers are unflagging a suspicious product, then Onetrail should be involved
- Optionally specify textual reason when unflagging
- History for unflagged products (nice2have in the dashboard, mandatory for backend)
- Keep track of the history of the unflagging
- In case of duplicate error (single seller, different SKU’s), the seller can select the single product to process
- Check master-file against cust specific file. if not in master and in customer file then show error
Buyer dashboard
As a Product Exchange buyer
I would like to, in case of suspects and errors as described in story 1 and 2, be notified by mail and in the portal
So that we can monitor the data quality of our suppliers and Onetrail
Acceptance criteria

- Send once a day
- Overview of conflicts which Onetrail is checking
- Dashboard:
- Filter on headers

- Filter in search bar to hide suspects or errors;
- Export to Excel with the current selection (filtered output)
