Generating Amazon Parent SKU

Products and their product-based variations have common models and matching fields. 
Amazon also uses an additional parameter for combining product based variations with the main product - 
Amazon Parent SKU. This parameter should be common for product-based variations.
 
To create Parent SKUs for products:

1. Create a generator template (Title template):
   • Go to Title Templates
   • Create a new template using matching fields for Parent SKU, Like Model code, Gemstone Code, 
     and a Free Field ending, e.g. "Parent". 
     
     For example:
     For a listing with metal variations only, model and gemstone should be the same for each variation.
     In this case for Parent SKU use fields: Model code, Gemstone Code and Free Field "Parent".
     Such a template will create the same Parent SKU for each variation product.
     In case the listing has variations by Gemstone Code too, don't use Gemstone code in a template,
     otherwise, Parent SKUs will be different.
     
     
     
2. Generate Parent SKUs:
   
   
   • Select relevant products in Catalog
   • Apply created template for Amazon Parent SKU
   • Check results in the batch
