Shared Data Set - change in dataset for one report

Hello,

I use a shared dataset for several reports. 

Why? So I can publish different reports separately from eachother and from the dataset, and I can grant permissions separately as well.

How?

- I have 1 pbix A file with the dataset (also a report on it, but does not matter in this case I guess).

- I have 1 pbix B file with visuals in different sheets, linked to the dataset in the other pbix file. 

However, now I have for instance a datatype that I want to change in the visuals of report in pbix file B. I did change the datatype now in file A, but how do the changes manifest in my visuals/reports
