# Setup: Supplier mapping rules

This guide explains how to set up and maintain supplier mapping rules in Norce Commerce, which is essential for proper product retail integration with suppliers.

## Required steps

- [Configure suppliers](/setup/suppliers) and [business rules](/setup/supplierbusinessrules) for supplier data
- [Import initial products](/setup/supplierproducts) into supplier catalogs


## Preparations

- Ensure suppliers are configured in the system and the correct business rules are set up.
- Import and initial full or at least a representative feed of supplier products (for the suppliers you want to map)


## How-to

### Access supplier mapping

1. Navigate to Suppliers -> Supplier Mapping in Admin
2. Select a supplier from the list
3. Choose either Category mapping or Manufacturer mapping


### Map categories

1. Review the list of unmapped categories
2. Select an unmapped category
3. Map it to the appropriate category in your category tree
4. Repeat for all relevant unmapped categories


### Map manufacturers

1. Review the list of unmapped manufacturers
2. Select an unmapped manufacturer
3. Map it to the correct manufacturer in your system
4. For unwanted manufacturers, mark them as "ignore"


### Further configuration

- Configure auto-mapping rules to automatically map categories and manufacturers during import
- Set up automation rules for supplier articles (see below)


## Important considerations

- *Mapping is an ongoing maintenance task, not a one-time setup*
- New unmapped categories and manufacturers may appear as suppliers update their catalogs
- The latest import from a supplier matters for the unmapped display. Older categories or manufacturers are not shown.
- Not all categories or manufacturers need to be mapped if certain product segments are not relevant
