New Set ID not visible in Control Data Setup pages in PeopleSoft

When we create a new Set ID from PeopleTools - Utilities - Administration - Table Set ID they don't just be available in the control data setup components like Department, Location, Jobcode etc. unless we map it with a Business Unit.

Didn't get it ?

Let's understand with a simple exercise.

1. Create a new Set ID as SET01 ( PeopleTools - Utilities - Administration - Table Set ID)
2. Go to Department Setup page ( Setup HCM - Foundation Tables - Organization - Department)
3. Click on 'Add New Value' 
4. Click on Set ID prompt and try to search the newly created Set ID SET01
5. Set ID cannot be found here.

Now do this:

1. Create a new Set ID as SET01 ( PeopleTools - Utilities - Administration - Table Set ID)
2. Go go Business Unit setup page (Setup HCM - Foundation Tables - Organization - Business Unit)
3. Open an existing BU or create a new one
4. Assign the newly created Set ID SET01 in the Set ID field under the section 'Default Record Group Set IDs'
5. Go to Department setup page (Setup HCM - Foundation Tables - Organization - Department)
6. Click on 'Add New Value' 
7. Click on Set ID prompt and try to search the newly created Set ID SET01
8. Set ID is visible this time

That's because we have mapped it to a Business Unit and it became a valid one.
