Product type in forwarding settlement document

Dear All

Working on LSP scenario, where LSP has different product type (For E.g Standard Land Transport, Express Land Transport and so on). Each of these product types has its own profit center.

Now the query is that when the forwarding settlement document is moved to ECC, under which field the product type will be passed so that revenue is posted to the profit center belonging to the product type.

Thanks in advance
