Fixed – VS402356: You do not have the permissions required to perform the attempted operation on this process (Azure DevOps)

We would get the below error while trying to modify states in the Azure DevOps process.

VS402356: You do not have the permissions required to perform the attempted operation on this process

To fix this we can add the user to the Project Collection Administrators group.

Or better give Process specific permission to the user

As a result the user can now add and update the process.

Hope it helps..
