To link custom data fields from PlentyONE (e.g. properties or the base price) with specific fields in Shopify (especially metafields), you use the "Input Field Mapping" wizard. This is necessary to transfer additional information during the article export that goes beyond the standard fields.

Important note: You can only create one mapping per run of the wizard. For each additional link, you need to start the wizard again.

This is the general procedure:

1. Open the menu Setup > Wizards > Omni-Channel in your PlentyONE system.
2. Start the Input Field Mappings wizard.
3. In the step "Create New Input Field Mapping", select the Shopify target field (e.g. "Metafield").
4. Then, in the step "PlentyONE Source Input Field", select the corresponding data field in PlentyONE to be exported.
5. Complete the wizard to save the mapping.
