Priorities - Oracle R12.2

Hello,

we want to use extra custom rules for prioritisation of sales orders based on specicific business rules, when planning runs. (we will use also plannig based on priorities (sales order, request date) but then with extra rules as well)

Per my understanding we need to use the :

Data Collections Hook

but I don't know which field we need to populate

if I use in the sales order in ebiz R12 the field planning_priority (eg I put in there 100) --> I do not see this field in MSC_demands, msc_sales_orders  (I see order_priority ... but not sure if this is the one used ?) so if I use the field planning priority on my sales order , to which field does it correspond in the above tables ?
