Unexpected Model Size Increase After Updating Custom Time Range

Hi Anaplan Community,

I recently updated a custom time range in my model and noticed an unexpected increase in model size.

Previously, my custom time range started in FY22 with 4 periods, and the total model size was 78 GB.

After updating the start period to FY23 (keeping the number of periods at 4), the model size increased to 87 GB instead of staying the same.

I expected minimal change since the number of periods remained constant. Has anyone experienced a similar issue, and what could be causing this increase? Could it be related to hidden data retention, formula recalculations, or Anaplan's memory allocation behavior?

Any insights or recommendations on how to find the root cause of this size increase OR how to reduce the model size after such changes would be greatly appreciated!

    Great question…Let me ask you a question, are you using Native Versions with Switchover with this time range? If so, that makes sense because you now have more "out" time periods than before. Before the change, you had more "Actual" data and therefore the system referenced those periods (not counting them). With the more forecast data (non Actual), the size of the model should increase.

    @rob_marshall,

    Ah I get it! And yes, we do in fact have a good number of modules using the native Versions (with Switchover) with this time range.

    Well noted. We are now exploring ways to optimize the model post size increase. Thanks, Rob!
