What access does a user need to be able to import articles to a knowledge base?

`sn_knowledge_import` is not an out-of-the-box role or permission explicitly used for controlling knowledge article import access.

`sn_knowledge_contribute` is a role, but the specific authorization for importing articles is typically managed through the 'Can contribute' User Criteria defined on the Knowledge Base record itself.

Within ServiceNow's Knowledge Management, access to perform actions like importing articles is governed by User Criteria. Users must be part of a group or possess a role that grants them 'Can contribute' permission to the target knowledge base, allowing them to create, edit, and import articles.

'Can import' is not a standard role or permission within the ServiceNow Knowledge Management system for article imports.
