I am using the vba code Activeworkbook.Refreshall in order to refresh the Power Pivot data sources.
However, I can see that not all sources are refreshed, even though no errors are shown.
It seems like all these data sources are .csv files. When refreshed individually, no errors are given.
I've made sure that "refresh this connection on Refresh All" is checked.

Any ideas would be much appreciated.
