How to Retrieve All Files Attached to a NetSuite Record

While NetSuite's search functionality (including SuiteScript 2.x's N/search module and UI-based saved searches) allows filtering files by the records they are attached to using 'File Fields...' filters or search joins, direct iteration of the 'Files' sublist is not scriptable. To enable programmatic access to file IDs, consider implementing one of the following custom development strategies:

1. Gold Solution (Suitelet)

   Implement a Suitelet screen where users create or attach files. This screen would allow users to select the record and the file, then attach the file via scripting to the record. Concurrently, maintain a list of custom records that store the association between the parent record and the file IDs, ensuring easy access to these IDs.

2. Silver Solution (Custom Record)

   Create a custom record specifically for associating records with file IDs. This custom record can be displayed as a child sublist on the parent record, allowing users to add file associations directly.

3. Bronze Solution (Custom Field)

   Utilize a custom field with a list of Document (files) where users can multi-select the files they wish to attach and associate with the record.
