Hi Neha,
please check in TRM following points:
1) Planning Tab:
All Participants ( managers ) should have subordinates which are assessed against potential and performance. Also Talent Group nominations should be done by the managers.
2) Preparation Tab:
Check the Talent monitor. The monitor ( on the left side) should show the managers and their subordinates which are nominated as talents.
Next Step is: Assign the talent to the agenda (on the right side ) Check the small icon next to the talents name.
Only if these steps successfully performed the talents will be displayed in the talent interactive grid.
Hope that helps
Martin Hastik
