What are the Data warehouse (DWH) retention times /policy?
Release : Any
In the Clarity product there is no retention dates on DWH fields.
This means that the data will remain indefinitely in the DWH database until removed.
There is a job called Load Data Warehouse that will import data from Clarity to the DWH database
To control which data goes in the DWH you have to check the Administration - Time Slices and the slice requests that are enabled for DWH (there is a checkbox). This will show you the range of data that is currently included.
Note that the slice requests roll over every month (typically) so say if you have selected 2 years worth of Actuals (24 monthly periods), the 2 years data will move forward every month. So you can configure this based on the retention policies your company has.
We do recommend testing any slice changes on your lower environment first before applying in Production.
In summary, the data in the DWH is kept permanently, with the addition that the Load DWH job will also remove / add /update data based on the selected time slice range. So the data you see is updated every time the job runs.
