How do i restrict sub users from changing the estimated time

I have created a project and have assigned tasks to sub users,how do i restrict the sub users from changing the timeline and other text boxes data.

Hi @Rakshith_Onkar,

Please go to the Role Permissions Manager. Select the role for which you want to restrict the sub-users access. Scroll down to the “Permissions for Document Types” section and select the document type “Task”. Under “Permissions”, uncheck the “Write” checkbox for the “Timeline” and other text boxes you want to restrict access to.

I hope this helps!
Thank You!
