Native database queries are run multiple times when refreshing
Thanks Xiaoxin
A good thought - I gave that a try - unfortunatly what that does is stop the data refreshing - I thought if I switched off refresh on Table 2 then table 2 would still pick up the refresh done in Table 1, but what happened was that Table 1 had the new data in it and Table 2 still had the old.
I then tried it the other way round switching off refresh on table 1 and switched it on for Table 2 got a surprise - table 2 had the new data in it - even though Table 1 still had the old data in it - proving that where one Table is based on another what Power Query is doing is taking the Script fromTable 1 and prefxing that onto Table 2 - rather than taking the data fro Table 1
So I guess what I want to do is impossible - I will need to think of another way of addresssing the problem.
Hi andrewsimmans,
Did you test below steps?
1. Get data from datasource. (source table)
2. Create a duplicate query of source table and named it to backup xxx, then cancel the refresh option of current query.
3. Modify the original source data and refresh the source table.
4. Repeat steps 3,4.
After above steps, you can see the history data(backup xxx), but I found it seems only works on powr query side. If you apply the change and return to the report view, these table will show the newest data as same as source table.

Anonymous this is not an acceptable solution as we have to modify our several reports just because of a bug of your app.
The real question is : why does a report, including only 1 query, which is associated to 1 table, runs this query multiple times ? And by multiple times I am saying that queries are sometimes run 2 times, sometimes 3 times, etc.
We want you to provide us a real technical solution to this software issue.
