How to handle duplicate in incremental refresh


New data coming through incremental refresh was creating duplicates. because of this my relationship fails and incremental refresh did not do well.

I only need to keep the data coming form the current refresh and delete the old data coming form incremental refresh.

I have tried multiple approach to solve this problem. FInally ended up in thinking of sorting the table in descending of the date column and removing duplicates ID’s will make the refresh smooth and faster. But I could see this causing a query folding issue.

is this a correct way to approach this problem, or is there any other way to do this.

you guidance will be much useful for me.

@Abishek , if you need only new data, then do not do incremental setting, it will be replaced with new data.


Incremental is only needed if you need to delete and append.
