Summary:

Content (please ensure you mask any confidential information):

Dears,

We would like to hide the Manager questionnaire of the PD to the partecipant.
On the PD template, in the Structure Section, we can not change the values for the Matrix Manager (partecipant) as in attachment.

Then, we noticed that there is the possibility to unflag the checkbox on the Performance Roles task but for us is greyed out, why?

Could you kidly help us to solve it?

Regards,
Paola
