SANA (Add-on) supports filtering of products on a product list page, based on product attributes. For each product attribute, one or more attribute values can be specified in order to filter the results on the product page (based on attribute type and configuration). AX2012 does not support specification of multiple product attribute values for a specific product. This prohibits the following scenario. SAP does support this scenario and thus the SANA shop can show in which machines certain parts are used.

Imagine you have 10 machines. You also sell spare parts for these machines. Ideally, you'd want to specify for each spare part to which machines (note plurality) this product applies, so when opening the spare parts list page on the webshop, you can filter (check checkbox(es)) the machine(s) you're interested in buying spare parts for.
However, by default, you can only specify one applicable machine as a product attribute value (assuming you enforce referential integrity through using a product attribute type that uses fixed values). 
To overcome this issue for now - although not ideally - we had thought of the following work around.
For each spare part product (i.e. all products in the spare part procurement category hierarchy), introduce product attributes 'Is applicable to <machine A>?' with a value either true or false. This would allow us to create product list pages in SANA Admin for each of the 10 machines, which would only display spare parts/products with their respective product attribute value set to true.

- Is there any way to accommodate this scenario using filters in SANA backoffice, instead of filtered product list pages? We would like to show a single filter criterion (i.e. 'Applicable machine', instead of 'Applicable to machine A?' true/false, 'Applicable to Machine N' true/false etc.)
