Hi,
Have set up incemental refresh on a table and first refresh completed and had sql similar to below.
Expecting subsequent incremental refreshes to be much quicker
When look at database (oracle) looks to have similar sql to initial load ....<1000
Is this expected?
Had been expecting to see somewhere in the sql the RangeStart and RangeEnd parameters as set to store last 2 years worth of data but update data in last 2 days hence would have expected to see >= '11-MAY-2020' AND < '13-MAY-2020' or similar

Hi @po ,
Incremental refresh is based on transferring the partition filter to the data source system to reduce the amount of refreshed data. Once the source data don't support query fold, the entire data is refreshed into power bi memory.
SQL-based data sources (such as SQL, Oracle, and Teradata) can determine whether the incremental refresh can be performed normally by viewing the warning when configuring incremental refresh.
