Defaulting Rules on Sales History

Hi All,

We are running Demantra.

We have got a big change coming in in the defaulting rules on Order Management side for our biggest customer.

Problem is Demantra collection is not respecting changes and going by the actual warehouse on sales order.

We need to apply the defaulting rule logic setup in Order manegement side on the sales history for this customer before loading data to Demantra.

Is there any standard API or process that can be applied in Demantra collection hook to achieve this?

This is urgent !!!

Any input on this is much appreciated.
