Refreshing data by import modus crash

[MarkVerwer]

My dataset has a gateway to a personal database on a server. By refreshing the data (with modus directquery) it all works fine. Refresh time = 2 minutes or less.

But i had to switch to import modus because of unpivot functions on a reference table.

With this modus, the refresh is crashing (after 45 minutes or so) and the error message is just "Something wrong, try again later".

With details:

Im trying to refresh a table with 100k records. 

Is there any solution to unpivot with directquery OR can someone help me with solve the crash?

Hi  @MarkVerwer ,

The refresh of the two connection modes of Import and Direct query is different.

Direct query:

If you are using the DirectQuery Mode, the report should query data source to get the newest data when you access the report or refresh the report

https://docs.microsoft.com/en-us/power-bi/connect-data/desktop-use-directquery

If you are using the Import Mode, it is to import data into Power BI for storage, which is equivalent to a copy or snapshot. When refreshing, go directly to Power BI to get the data without communicating with the data source.

To use unpivot in Direct Query, you can refer to the following link:

Thanks.

First i selected a table with DirectQuery and then "copied" the data to another table with;
= Table.SelectRows(ORDERS, each Date.From([DELIVERYDATE]) > Date.From("01-01-1970")) (with import)

then i could use some pivot and unpivot functions.
