I have a report with 2 tables. The 2nd table contains visual calculation (I'm computing a % delta with previous line

( ([qty] - (PREVIOUS([qty]))) / PREVIOUS([qty]))*100 and in PowerBI Desktop all works as expected. I've tried to load it on my Power BI Report Server, but there only the 1st table loads correctly. The 2nd fails with following error message :

The query contains unsupported visual calculation expressions. Either the model capabilities do not support visual calculations or the visual calculation feature switch is off.

PowerBI Desktop : 2.138.1452.0 64-bit (novembre 2024)

PowerBI Report Server : Version1.22.9153.7886(Janvier 2025)

Any idea on this issue?

Thank you
