Can User-Defined Attributes (UDAs) be uploaded at the part level? If so, how can they be uploaded, and where can the uploaded UDAs be viewed?

• Yes, you can now upload User-Defined Attributes (UDAs) to the Customer Part level. 
• Just as you classify suppliers and sites with your own custom attributes, you can now add/attach your own business dimensions — such as business unit, category manager, plant, or product family — directly to your customer parts. 
• This lets you organize, segment, and filter your part portfolio using the vocabulary your organization already uses internally.

      How to upload part-level UDAs:

• Part-level UDAs are ingested exclusively through Dataflow Integration (DFI).
• Unlike Supplier and Site UDAs — which can be managed via the UI, CDIF, or DLA — Part UDAs are supported through DFI only.
• The UI / data-loader setting under Settings → Load Data → User Defined Attributes governs Supplier and Site UDAs only; it does not affect how part-level UDAs are ingested.
• Part UDAs sent through any non-DFI path (CDIF or DLA) will not be processed. 

     Where you'll see them:

       Part-level UDAs appear on the Customer Part Listing Page as filterable columns. You can:

• Upload your part-level UDAs as columns on the grid
• Filter the page by one or more UDA values to narrow the view to exactly the parts you care about
• Combine UDA filters with existing part fields to segment your portfolio (for example, isolate the parts owned by a single business unit, or view only the parts assigned to a specific category manager)

     Currently part-level UDAs are surfaced as columns and column-level filters on the Customer Part Listing Page. 

• Part UDAs configured via Dataflow Integration (DFI) are displayed only on the ‘Customer Part Listing’ page. 
• Part UDAs show up similarly to how supplier and site UDAs are displayed on their respective listing pages 
• Currently, filtering is only accessible via the ‘UDA columns.
