Deleting PSA data

Hi All,

We are planning to delete the data in PSA as we are running out of space, all our loads are delta loads from PSA, so I don't see any problem in wiping out the PSA data .Am I correct?Do we need to take care of anything else beofre we wipe out the PSA data.

Thanks

Pradeep

    Hi,

    After loading data into Data Targets from PSA, you can delete data. it's better option to increase the DB performance.

    To delete PSA data only when you are sure about its reliability and correctness of your loading process.

    Yes, data in the PSA tables is periodically deleted to prevent it from getting bigger and bigger.

    It is a good idea to delete incorrect requests or deltas for a data target, to which you do not want to load any more delta.

    PSA Data can be deleted ideally as soon as a data load is complete. For a load from Datasource to ODS / CUBE you can have a separate PSA and from ODS to Cube your change log is your PSA.
