Type defining the relatedProductGroup container, which contains detailed information on a related product group. Related product groups are tied to the primary product in a product bundle, and there can be multiple related product groups in a product bundle.
This integer value controls (in request) or indicates (in response) the placement of the related product group in the primary product listing. If the rank value(s) are not specified for related product groups, the placement of the product groups in the primary product listing will coincide with the order in which the related product groups are listed in the createBundles or updateBundles calls.
The seller includes and sets this boolean field to 'true' in createBundles or updateBundles calls if the product group discount only applies to a specific product in the product group. If this boolean field is 'false', it indicates that the buyer can select multiple products within the product group and still be eligibile for the product group discount. For single SKU discounts, radio buttons will appear adjacent to each product of the product group in the primary product listing. For multiple SKU discounts, check boxes (for multiple selections) will appear adjacent to each product of the product group in the primary product listing.
This field is only returned in findBundles and getBundles calls if 'true'.
