"Create article" dialog in Workspace pulls from kb_knowledge_base records, and the key to filtering is the Table field on each Knowledge Base record.
Step 1 — Set the Table field on each Knowledge Base
Navigate to Knowledge > Knowledge Bases (kb_knowledge_base.list). Open each knowledge base record and set the Table field to the specific child table of kb_knowledge that it should be associated with (e.g., your custom child table like u_my_kb_article). If a KB should only appear when creating articles on a particular child table, this field must be populated with that table name.
Step 2 — Verify the Reference Qualifier on the dialog
If setting the Table field alone doesn't resolve the filtering in Workspace, you may need to add or adjust the reference qualifier on the Knowledge base field in the dialog. The OOTB qualifier should ideally respect the table column, but if it doesn't, you can add a reference qualifier like:
table=javascript:current.getTableName()^ORtableISEMPTY
This ensures only KBs mapped to the current child table (or KBs with no table restriction) appear in the dropdown.
Step 3 — Workspace-specific configuration
In Workspace (Next Experience), this dialog is typically driven by a Declarative Action. To modify the reference qualifier:
- Go to sys_declarative_action_assignment.list and search for the action related to "Create article" or "Knowledge article creation."
- Trace it to the associated form or modal configuration.
- Apply the reference qualifier on the Knowledge Base field at that level.
Alternatively, if the dialog is rendered through a UI Action or Record Producer, look for the script or variable definition controlling the Knowledge Base field and update the reference qualifier there.
Important note: Make sure the table field on kb_knowledge_base is set to the child table name (not kb_knowledge itself) for each KB you want filtered. KBs with the Table field left empty will typically appear for all tables.
