Hi All! How can we set Goal flexfields to VIEW-ONLY in a specific performance document task? We have tried with Page composer: (view attachments) the goal is to set the flexfield to READ-ONLY in the specific task of the performance document but it's not been working.

How can we achieve this goal?

Thank you so much for any suggestion!!
