Hi Team,
Our business user- Facilitator have raised concern regarding the incorrect rating showing for few colleagues in the report for one of the Talent Review Meeting. Not sure if any facilitator created and deleted the Talent Review meeting leading to this.
We want to edit and correct the ratings of one of the colleagues for Talent Review Meeting which is already completed.
Option-1: When we try as Facilitator and reopen the Talent Review Meeting to change the rating, it erases the data for all the colleagues.
