What role or privilege is needed in order to add or edit a project asset?

Summary:

We just implement the project capitalization in our client. We are creating project assets in the capital projects manually or via the spreadsheet. We are able to do it because we have the project administrator role in our user accounts (implementers).

Content (please ensure you mask any confidential information):

In line with the summary above, we have an on going UAT for our current rollout and the users are unable to add/create a new project asset or edit an existing one even though we have assigned both the Fixed Asset Administrator role and the Project Administrator role. This is working on our side but not on the user's side. We already ran the LDAP processes to reflect the user roles changes on the user accounts but still they only have the view/read only access.
