Problem with incremental refresh on power bi premium

Hi everyone
I have a problem with incremental refresh on power bi premium.
I have set an incremental refresh on my power bi desktop (the aim is to refresh data of 2 last days) .
on power bi desktop, all works correctly but when I publish, the data is duplicated (for example on 2019-07-01 the amount of sales is duplicated by, 2)
Have you an idea about this problem?
The refresh of data is done every 30minute and the data is duplicated by 2 every time.

Thanks in advance for your help

hi @SLI 

Do you have a specific date column defined as LastUpdated date and specified the incremental policy in a the relevant table? Also make sure you have loaded the hisotrical data and refresh rows in the last ( XX) days.  detect data changes also critical to LastUpdatedDate changes.

Hi, I have the same problem, were you able to fix this? I have a single INSERT_DT column which I am using for my RangeStart and RangeEnd filter, my settings are keep last 2 years of data and refresh for the last 2 days. It runs once a day, but all the daily snapshots are getting duplicated

Hi @oscarmqz 

 

yes my problem was resolved by adding a new column (dateLastUpdate) that i used for my RangeStart and RangeEnd filter

this column isn't updated in the source data, it shows only the last date of the update

 

please refer to this documentation

https://docs.microsoft.com/en-us/power-bi/service-premium-incremental-refresh#filter-date-column-upd...
