Selecting Classifications Manually
Learn how to select one or more product classifications and validate all products within those classifications using the Qmica Validation Engine.
The manual selection method allows you to validate products based on their GS1 classification. Instead of selecting individual products, you choose the classifications you want to include in your validation set.
You can select multiple classifications and validate all associated products together, making this method particularly useful for checking complete product categories or assortments.
How to create a validation set manually
The process consists of six steps:

Step 1 — Create a Validation Set
- Navigate to Validations in the Qmica main menu.
- Click + Create a validation set.
- Enter a descriptive name for your validation set.
- Select Select manually as your product selection method.
Qmica opens the classification selection screen.
Step 2 — Search for Classifications
The classification selection screen displays the available classifications.
Use the search field to find the classifications you want to validate.
You can search by:
- Classification code — Enter the relevant classification code.
- Classification name — Enter part of the classification description.
The list updates to show matching classifications.
Step 3 — Select One or More Classifications
- Locate the classification you want to include.
- Click Select next to the classification.
- Repeat this process for any additional classifications.
You can select multiple classifications within the same validation set.
Qmica will include all products associated with the selected classifications when running the validation.
Tip: Selecting multiple classifications allows you to validate a larger assortment in one operation instead of creating a separate validation set for each classification.
Step 4 — Review Your Selection
Click Show selected items to review the classifications you have selected.
The overview displays the selected classifications, including:
- Classification code
- Classification name
- Target market
Check that the correct classifications and target markets are included.
If you selected a classification by mistake, click Remove to exclude it from the selection.
You can return to the classification list to add more classifications before starting the validation.
Step 5 — Start Validation
Once you have reviewed your selection, click Start validation.
Qmica creates the validation set and starts checking the product data against the applicable GS1 requirements.
The validation set appears in the Validations overview while processing is underway.
Validation takes place directly within Qmica. You do not need to submit the products to GS1 to identify validation issues.
Step 6 — Review the Results
When validation has finished, return to the Validations overview.
A green checkmark in the Build column indicates that the validation build has completed successfully. It does not necessarily mean that every product has passed validation.
Open the three-dot menu next to the validation set to access the available actions:
- Show items — View all validated products and their individual validation status.
- Show issues — View validation issues grouped by issue type and identify affected products.
- Revalidate — Run the validation again after correcting product data or mappings.
Products with validation issues are marked as Invalid, while products that pass the validation checks are marked as Valid.
Next Steps
After completing the validation, continue with:
Understanding Validation Results — Learn how to interpret product statuses and validation issues.
Resolving Issues & Revalidating — Correct data issues and validate your products again.
Note: Manual selection includes products based on their classifications. If you want to validate only a specific list of individual products, use the CSV import method instead.
