I have following questions related to Edit Allowed parameter for Key Figures:
1. When should I use "System Editable" option?
2. I have a history key figure(stored and not editable) at base planning level of "DAY" but I want to load the key figure value at "MONTH". In this case I would need to set dis-aggregation expression (so that system disaggregates the value and stores at base planning level).As setting up of disaggregation expression is only possible for editable key figures, can I use "System Editable" option in this scenario?
