Defaulting Rules from 3rd party Application

Hi All,

We are trying to build an integration for a customer and need to invoke OM Defaulting rules from a 3rd party application.

All customer needs to the SSD and Shipping Warehouse.

There are bunch of Item specific rules in our OM Defaulting rules.

The application already have Customer Number, Ship To Location and Item Number.

Can I invoke any PL/SQL and pass the Customer Number and Item as parameters and return the return SSD and Shipping Warehouse?

Idea is to run defaulting rules BEFORE creating a sales order and evaluate the date and Shipping Warehouse. If this works fine then only create Sales Orders.
