Hello, I have an interesting challenge I am trying to solve.
Background:
- We have 4 Forecast versions.
- Version Forecast (3+9) means that the forecast has 3 months of Actuals and 9 months of forecasted data.
- Actuals data is loaded from a source system.

The Challenge:
How can we ensure that all data in the Forecast (3+9) remains locked when actuals data from the source system changes. So when we load the latest data into Anaplan, Actuals will change but data in Forecast (3+9) will not change.
Potential Solution:
I've created a new Temp (3+9) version so we can Bulk Copy Forecast (3+9) data into Temp (3+9) before the data is loaded. The idea is that we can then Bulk Copy from Temp (3+9) back to Forecast (3+9) after new actuals is loaded. The challenge with this is that it looks like we need to have the same switchover date in Temp (3+9) for the data in Temp to match the Forecast (3+9). We were hoping that we could then load the data into Forecast (3+9) with no switchover date, so this has been a road block.
Is this on the right track to solve this issue? Would you have any advice or other solutions?
Thank you!
