How to combine stock from several suppliers by SKU

2026-06-30
Task

Two suppliers send the same product with SKU LMP-2201, but in different files, categories, and stock values. You need one consolidated catalog product, source-level stock values, and one final available stock value.

Short answer

Load each price list as a separate consolidated catalog source, use SKU as the product identifier, enable Full source synchronization for complete supplier snapshots, normalize categories with transformations, and map stock values to supplier stock groups. Calculate final stock with a sum rule over the selected groups.

How to do it in Eofferix

  1. Create a consolidated catalog import profile for the first supplier and upload its price list. In What format to export?, open Applications and choose Consolidated catalog. Create a separate profile for the second supplier so each source has its own synchronization and stock contribution.

    Interpreter profile with Consolidated catalog selected as the application
    Consolidated catalog is selected in applications, so the source loads products, offers, and categories into the internal consolidated catalog.
  2. In Element identification, select SKU as the product identifier. If the file has separate offer rows, identify the offer by a stable SKU or the same article code.

    Selecting SKU as the product identifier in Eofferix
    The identifier makes the second supplier update the same product instead of creating a duplicate.
  3. In typical scenarios, choose Full source synchronization. This mode updates or deletes only the current source contribution: if the North supplier no longer sends the product, the North contribution is removed, while South supplier data stays intact.

    Full source synchronization in import settings
    Use this only when the supplier file is a complete current snapshot.
  4. Add transformations for categories. For example, normalize Lighting / Desk and Home / Lights into Lighting / Desk lamps. This prevents category naming differences from splitting the same product into different branches.

    Category transformation into one consolidated catalog category
    The rule replaces supplier-specific category names with one category path in the consolidated catalog.
  5. Map the first supplier Stock field to the North Supplier stock group and the second supplier field to South Supplier. In final stock settings, add a Sum rule for these groups.

    Select the supplier stock groups and the Sum all selected groups scenario.
  6. Run both profiles and open the product card in the consolidated catalog. SKU LMP-2201 should remain one product, with supplier stock stored as separate values.

How to check the result

  1. The consolidated catalog should show one row for SKU LMP-2201, not two.
  2. Open the product card and check the supplier stock groups and the final stock value.
  3. Run one source again without the product and confirm that only this source contribution is removed while the other supplier stays in the catalog.
