问题
In Power query I have table A and table B.
I have merged these to create table C and expanded to keep the column I need in my report.
When I refresh the data, it fetches data from the source database into all 3 tables.
It doesn't allow me to delete tables A and B because they are used by the merge table C.
I have tried both unchecking enable load on the tables A and B as well as unchecking include in report refresh. As mentioned here (see comment section on answer - What do "Enable Load" and "Include In Report Refresh" mean/do?), these options are effective only in power bi desktop and have no effect in power bi service.
So how can I prevent power query from fetching data for merge tables A and B so that it queries the source database only for table C?
