3464709 - Incremental Load

Symptom

When loading data there is a message, "The data query returns empty result set"

 Year1_Actual_data_Query
failed to refresh
The data query returns empty result set

Environment

SAC data management 

 import data from external data source

Cause

The date for the increment “Created On”, is based on the latest row value in the when the incremental load was run. When this is initiated it brings over all the existing data. Thus, after the increment is set there is no new data to import. 

Resolution

-Verify the right import method is in use. If update is in use, try append.
-Perform a manual refresh. The first refresh right after replacing or deleting the old incremental load filter will bring in the full set of data.
-Confirm a valid value is present for the incremental load filter after the manual refresh.

See Also

-create date is used outside the incremental process there are options for after/before and such. It might be that the project uses that setup also.
