Dataunit statistics

Can you please guide me the definition for the below points - 1) What is number of NODATA,Zero,Real,Derived cells ? And why are they all under NODATA Status ?

    • Real cells are intersections for which actual numbers have been stored or created.
    • Zero cells are real cells with a value of 0.
    • NoData cells are intersections that don't have data for one or more periods in the year but have (or have had) real data in later periods.
    • Derived cells are intersections that don't have data for one or more periods in the year but have (or have had) real data in previous periods.

    For performance reasons, you want to keep the number of NoData and Zero cells to a minimum, since they generate actual database records that have to be loaded and examined when calculating and consolidating.

    They are grouped under "nodata status" for convenience, since they are related from a logic perspective.

      Thank you for your answer. I have now implemented removezeros and nodata function in the calculations but still have a large zero and no data in the system which is ( calculated, durable and input). How do I remove Nodata and zero cell from the system.?

        You want to investigate api.Data.ClearCalculatedData. It has options to clear calculated data and durable data too.

        As for input data, that's stuff that was either imported or copied from other scenarios. You can clear it from the Import step (if loaded) or with api.Data.SetDataCell - look for the "Clear Data" snippet.

        One thing to mention is that you'll likely never be completely free of NoData and zero cells, simply because of how the system works. The objective should just be to keep them to a minimum, ensuring your rules don't create more when they run.
