Unsuccessful refresh

[janschovanek]

Hello,

I am having problem with data refresh in PBI in last few days, is there anyone, who could helps me with my problem?

Facts:

- I have around 20 tables (19 tables are loaded from database, 1 table is loaded from file)

- I have around 15M rows, each table has around 10-15 columns

- In each table we have around 2-3 counted values (which simply can't be measures)

- Data model (.pbix file) has around 0,5GB

- I set up classic gateway (not the personal mode), but I also tried personal gateway

- Gateway is installed on server with 32GB RAM

Issue:

- When I am trying to refresh data, I get errors - mostly "out of memory" errors, I also get "internal error" and also "cancelled by user" even I didnt stop the data refresh

- When I was looking on the server during the data refresh, in RAM is around 6-7GB (around 20% of RAM), processor is working on maximally 10% of its performance.

- When I manually refresh data, PBI acts wierdly. After few minutes I can see in the left menu that refresh is successfully completed, but when I get into "sheduled refresh" menu, where is detail about refresh, I can see there "still refreshing". After next few minutes I see in this detail and also in the left menu that refresh was unsuccessfull due to those errors (most of times I get Out of momery error😞

1) Out of memory:

3) Internal error

[I cant see detail of error now]

What I already found

- I already set in my model bigger Data Cache Management Option to 24488 MB

- I already unset in my model paralel loading of tables

- I already unset downloading data preview on background

- I also found how to possibly optimize datamodel for memory, but since I dont have problem with RAM, I dont really understand this problem.

Can anybody explain me the problem and help me with some solution?

Thank you.
