Read Configuration details in Sales Order creation mode

Hi Experts,

I am creating a Sales order for a Configurable material. I have entered configurable material number in the Sales order and it goes to configuration. I will key in all the required characteristic values and come back to the Sales order. Before I save the order, I want to read all the characteristic values in the sales order user exit or pricing routine.The requirement is to apply pricing based on few characteristic values.

I have tried FM's VC_I_GET_CONFIGURATION_IBASE and VC_I_GET_CONFIGURATION.

But this will pull conifguration data after the Sales order is saved and committed to the database.

Appreciate if you can provide any inputs.
