Simulate order routing like tcode CU50

Hi Gurus

I have a requirement very special.

I need to simulate que order routing of a comercial document that has no yet created an production order. This simulation is perfectly recrated on transaction CU50, because it gives me the resulting routing based on the sales document configuration.

Now what I need, is a way to replicate/use the CU50 transaction on an abap program that retrieves the resulting simulation routing of several sales documents.

I don't know if this is posible via LSMW o FM o BAPIs

hope someone have a useful idea.
