automatic report having only 2000 row even in csv

automatic report having only 2000 row even in csv

Hi,

When I run a planned report, I obtain a csv with only 2000 rows. however, when I run it on the portal, I obtain all the 3800 lines in the csv. Why is there a difference between the two? It should be the same number of lines right?
Would it be another way to achieve this and have all my lines on a report?

Thanks,
Stanislas
