Hi Laurine

To a specific user or group, I do not believe it is possible but you can leverage the "level" feature to achieve something similar.

You can check this help page DataMiner Help - DataMiner to see how you can configure it for your users.

And you can see more details about how to configure it in your protocol here DataMiner Help - Development

For this part, you should be able to add the level attribute to the write parameters you do not want the users to have access to.
