Assignment Group field is empty on Work Order Tasks in EAM

[usernotfound445]

Hi everyone,

I'm facing an issue in ServiceNow Enterprise Asset Management (EAM) where the Assignment Group field is appearing empty/blank on the Work Order Task form.

I have checked the Work Order level, but the group is not auto-populating or available for selection in the tasks. Could anyone guide me on:

1. Is there a specific Assignment Rule or Client Script that controls this?

2. Are there any missing configurations in the Work Order Template or Asset Task flow?

Any help would be appreciated. Thanks!

Try this -
Right-click the Assignment Group field → Show - Reference Qualifier. See what encoded query is filtering the list. It's likely filtering by location, company, or work type with no matching groups.

Other things to check:

• Parent WO (WO0010013) — is Assignment Group set there? Tasks often inherit from the parent via a Business Rule on wm_task.
• Task Template (wm_task_template) — open the template that generated this task and verify Assignment Group is populated on it.
• Assignment Rules — check System Policy → Assignment for any rules on the wm_task table.

Most likely fix: Adjust the reference qualifier on the Assignment Group field in the wm_task dictionary entry to be less restrictive, or ensure your location/work type combination actually has matching assignment groups configured.
