Question 1

What causes Field Not Visible on Form in ServiceNow?

Accepted Answer

Field-level ACL denying read access — Navigate to System Security > Access Control (ACL) and search for ACLs on your table with the field name. Look for ACLs with type 'read' that have role conditions excluding your current user. Field not added to form layout — Check if the field exists in the form sections by opening Form Designer on your table. The field may exist in the dictionary but never been added to any form view. UI Policy hiding the field — Navigate to System UI > UI Policies and filter by your table name. Check all active UI Policies for actions that set your field to 'Visible=false' based on conditions. Dictionary entry is inactive — Go to System Definition > Dictionary and search for your field on the target table. Check if the 'Active' checkbox is unchecked in the dictionary entry. Field exists on parent table, not current table — Verify you're looking at the correct table by checking System Definition > Tables. The field may exist on a parent table but not be inherited or available on the current table's forms. Client Script or Catalog Client Script hiding field — Check System Definition > Client Scripts for any scripts using g_form.setVisible() or g_form.setDisplay() to hide your field. Search for scripts active on your table.

Question 2

How do you fix Field Not Visible on Form in ServiceNow?

Accepted Answer

How to fix it First, verify the field exists in the dictionary. Navigate to System Definition > Dictionary, search for your table name, then locate the field. Confirm the Active checkbox is checked. Check ACL restrictions by going to System Security > Access Control (ACL). Filter by your table name and look for any ACLs with Operation = read that reference your field name. Open any field-level read ACLs you found. Check the Requires role field and Script condition. If your user lacks the required roles or fails the script condition, the field will be hidden. To temporarily test ACL impact, impersonate a user with admin role or modify the ACL to add your current roles to the Requires role list. If ACLs aren't the issue, check the form layout. Navigate to your table's form, right-click and select Configure > Form Layout or open Form Designer from the gear icon. In Form Designer, look for your field in the Available Fields list on the right. If it's there, drag it to the desired section on the form. If it's not in Available Fields, it may be restricted by ACL or be on a different table. Check for UI Policies that might be hiding the field. Go to System UI > UI Policies and filter by Table = [your_table] and Active = true. Open each UI Policy and click the UI Policy Actions tab. Look for actions where Field name matches your field and Visible = false. If you find a UI Policy action hiding your field, check the UI Policy's Conditions tab to understand when it triggers. Either modify the conditions or change the action to Visible = true. Check if the field exists on the correct table. Go to System Definition > Tables, find your table, and verify its Extends table value. The field might exist on a parent table that doesn't inherit to your current table. As a final check, look for Client Scripts that might be hiding the field. Navigate to System Definition > Client Scripts and search for scripts containing setVisible(false) or setDisplay(false) with your field name.

Question 3

How do you prevent Field Not Visible on Form in ServiceNow?

Accepted Answer

Always document ACL changes with business justification and include field visibility impact in the ACL description. Create a standard naming convention for UI Policies and include field visibility rules in policy descriptions. Use Form Designer's 'Add fields' feature immediately after creating new dictionary entries to ensure they appear on relevant form views. Set up automated testing scripts that verify critical fields remain visible after platform updates or customization changes. Maintain a field visibility matrix document that maps sensitive fields to required roles and access conditions.
