Proportion Series - Matrix - Functionality

Hello All,

I have a big doubt regarding the proportion.
I want to know if demantra use the below secuence

1) Use the proportion by series, unless all instances are 0 or null (in the DB, not what customer sees)

2) If they are zero or null Use matrix glob_prop proportions, unless all glob_props are 0 or null

In this case, the demand history (which affects glob_prop) for these combinations are driving the percentage of splits

3) use equal split

All combinations below the aggregated level will get an equal split

or I need to set up how Demantra split the data in the lowest levels.
