Oracle OOTB Finance Driver based Planning

Summary:

Hi Experts,
I have a scenario where my customer wants to understand if there could be any performance issues when using Oracle’s out‑of‑the‑box Finance and Planning driver‑based models with around 600 accounts. The approach involves keeping calculation logic in member formulas and storing members, while triggering rules either through the Calculate Form option or via business rules using CALC DIM.
Initially, the plan was to use only about 150 accounts as drivers. However, due to ongoing business expansion and future considerations, they now need to evaluate scaling up to 600 accounts. They are looking for clarity on the potential performance impact of 150 accounts versus 600 accounts in a driver‑based planning hierarchy.
