Access Control Overview
Portal access depends on:
- ACLs
- HR Criteria
- Portal eligibility
- Correct Subject Person mapping
➡️ Failure of any one results in Invalid or Not Authorized.
Troubleshooting Steps-
1. Verify Subject Person Mapping
Check
- Table:sn_hr_core_task
- Fields:
- Subject person
- Opened for
- Assigned to
Expected
- Subject person = Employee (logged‑in user)
Fix
- Correct the Subject Person
- Assigned to may remain an HR group
2. Validate HR Criteria Access
Check
- HR Criteria on:
- Parent HR Case
- HR Service
Expected
- Employee included in Read + Write access
Fix
- Add user criteria such as:
- Employee
- All internal users
3. Confirm Task Is Employee‑Visible
Check (on HR Task)
- Visible to employee = true
- Hide from portal = false
Fix
- Enable employee visibility
4. Confirm Correct Task Type / Template
Check
- HR Task Type = Collect Employee Input
- Template is OOTB or portal-enabled
Fix
- Use standard Collect Employee Input task type
- Avoid internal-only or custom task templates
5. Validate Portal / Catalog Enablement
Check
- Associated catalog item / record producer:
- Active = true
- Available in Employee Center
Fix
- Enable for Employee Center
- Associate correct portal page
6. Validate HR Profile
Check
- Table: sn_hr_core_profile
- Profile:
- Exists
- Active
- Correct user reference
Fix
- Correct or create HR profile
- Ensure user is active
7. Check Portal Widget Security (If Custom)
Check
- Widget roles
- Page access rules
Fix
- Ensure role sn_hr_core.employee is allowed
- Remove restrictive role conditions
Quick Validation Checklist
✅ Subject person = employee
✅ HR Criteria allows employee read/write
✅ Task visible to employee
✅ Task type = Collect Employee Input
✅ HR Profile active
✅ Portal / catalog item enabled
