If you are seeing the following message in the LivePlan forecast, it means that you are a guest on someone else's company, and you are looking at a step that the owner (or a contributor) hasn't started editing yet:
In other words, there's nothing for you to view. It might be that the owner hasn't gotten to this section of the forecast yet, or it might be that the section just isn't relevant to them. For example, maybe the company doesn't have any direct costs, because it's a service business.
In any case, if you think there should be something for you to view in this section, you may want to consult with the owner of the company for more information. In general, as a guest, you have view-only access to another person's company, which means you can't add or edit anything.
