Resolving Issues & Revalidating

Step 1 — Identify the Validation Issues

1. Navigate to Processing → Validations.
2. Locate the validation set you want to correct.
3. Open the three-dot menu.
4. Select Show issues to review all detected validation issues.

The issues are grouped by type, allowing you to identify problems that may affect multiple products.

Expand an issue to see which products are affected.

Alternatively, select Show items to investigate the issues associated with an individual product.

Tip: Start with issues affecting multiple products. Resolving a shared issue may reduce the number of invalid products significantly.

Step 2 — Determine What Needs to Be Corrected

Validation issues generally originate from either the source product data or the mapping configuration.

Missing or Incorrect Source Data

Some issues occur because required information is missing or incorrect in the original product data.

Examples include:

• A mandatory attribute is missing.
• A product measurement contains an incorrect value.
• A required value has not been supplied.
• Two product attributes contain conflicting information.

In these situations, correct the information in your source system or source file.

After correcting the data, ensure that the updated product information is imported into Qmica before revalidating.

Important: A mapping cannot create missing product information. If a required source value is unavailable, it must first be supplied.

Missing or Incorrect Mappings

Other issues occur because source attributes or values have not been mapped correctly to the GS1 data model.

Examples include:

• A source attribute has not been mapped to the corresponding GS1 attribute.
• A source value has not been mapped to an accepted GS1 code.
• A value conversion produces an incorrect result.
• A required GS1 attribute is not populated because the relevant mapping is missing.

In these situations, review and correct the mapping configuration in Qmica.

Once a mapping has been corrected, the change can be applied to other relevant products that use the same mapping.

Step 3 — Resolve Issues Affecting Multiple Products

The Show issues view is particularly useful when several products share the same validation problem.

For example, suppose 150 products contain a source attribute called Colour, but the attribute has not been mapped to the corresponding GS1 attribute.

Instead of correcting each product individually:

1. Identify the shared issue in Show issues.
2. Expand the issue to review the affected products.
3. Check whether the required source values are available.
4. Correct the relevant attribute or value mapping in Qmica.
5. Revalidate the products to check whether the issue has been resolved.

If the source values are available and the corrected mapping applies to all affected products, a single mapping correction may resolve the issue across the entire selection.

Tip: Always check whether a recurring issue can be resolved through mapping before making individual product corrections.

Step 4 — Revalidate Your Products

After correcting the identified issues, run the validation again.

1. Navigate to Processing → Validations.
2. Locate the validation set you previously created.
3. Open the three-dot menu.
4. Select Revalidate.

Qmica starts a new validation run for the selected validation set.

During processing, the validation set displays a processing indicator.

Once the validation build has completed, a green checkmark appears in the Build column.

Important: The green checkmark confirms that the validation build completed successfully. It does not necessarily mean that all products are valid.

Step 5 — Review the Updated Results

After revalidation, review the results again.

Use Show items to check the validation status of individual products.

Products that pass the applicable checks are marked as Valid. Products with remaining issues are marked as Invalid.

Use Show issues to review any unresolved validation problems and identify the products still affected.

If issues remain, repeat the correction and revalidation process.

Step 6 — Prepare for GS1 Publication

Once the relevant validation issues have been resolved, your product data is better prepared for registration and publication to GS1.

Qmica's Validation Engine helps identify data quality issues before submission, reducing the need to rely on external GS1 feedback to discover errors.

However, a successful Qmica validation does not guarantee acceptance by every GS1 data pool or recipient.

Additional validation requirements or business rules may apply during registration or publication.
