New to powerbi rights questions

[locka]

Guys i'm sorry for newbie questions.

I've just been given access to PowerBI and have a number of reports i need to migrate from another reporting tool and excel. I can access a powerbi dataset that has already been created.

I've tried googling but i want to understand before i start working that if im creating dashboards. I want to try and link some columns from the data set together that are currently in different tables with in model section. However i want to make sure this would only apply to what im doing currently and not affecting the original dataset. I also want to make sure i cannot do any accidental changes to the underlying data.

If i can is there anyway to restrict this from me. I currently only want to read the data not modify it.

The beauty of PowerBI... It imports data. Yes you can transform data, but never in the data sources. Also you can develop from a copy of the original file. What can go wrong?
What surprises me is the fact a newbie is given such a task without proper support or supervision (it seems). I can only hope you do have such a support and that the required level of training is given.
PowerBI is not something you simply start doing without having some kind of relevant background.
Good luck with your challenge. I do advice to read some books on the subject.

EDIT: never apologize for asking questions. It's the purpose of the forum.
