User's visualization error - DirectQuery for Power BI Datasets and Analysis Services

Hi, I', having the same problem. 

I have a report published in my department workspace that is based in a dataset from another workspace. Everybody can acess it without problem. 

But, I created another one(based in the same dateset related above) that mix external data (Excel etc) that are in our sharepoint as a composite model, because we need more details/criterios. I published that report in our workspace but the some people who can use the report cited above can't see this new one, while another ones can. I don't know how to fix it!

Can someone help me?
