Global Text Search not working for scoped table but working for Service Portal

[reet2]

I have a scoped table- Test  extending from Template Table (which is extending from task) I have generated the index for the table and after I added this table as a search source for service Portal , it is giving results for the specific user.

I want the same field to be searchable for Global Search . I have configured the following steps.

1] Added the roles and table in Global Text Search properties.

2] Added the Search Group for application scope table.

3] Re-ran the Text indexing.

PS: Since it is inheriting from task eventually , I am trying to add scoped table in tasks search group which is not being allowed by the system.

Have I missed anything in the configuration steps? This is in ServiceNow Tokyo.

I encountered the same problem.
I tried to add the Story Table (rm_story) to the Global Search, I went to the Text Search Groups and and added the Story Table as Text Search Table in the Task record.
After that a message showed up that the Table needs to be indexed and that it started the index automatically.
In the Text indexes Table, was only the Task Table showing as Indexing, After the Indexing was Over it still didn't show any Story in the Global Search.

Is there something I did wrong, or why is it still not working?
