Disable Refresh

hi FilipeSantos_pt ,

One approach is to create measures in the Data view; this way reports/visuals will not refresh everytime you create a new or exit from an existing measure as seen in below screen grab

Another approach you can try is to create/edit measures with a focus on an empty report sheet.

This way visuals will not attempt to refresh everytime you create a new or exit from an existing measures

I have tried this approach with a report file with imported data and a report connected to a live dataset but out of network - and I am able to create measures without any errors. 

Let me know if I am missing any steps you are performing. Thanks!
