SD invoice - post on vendor account

Hello,

This is the situation I am currently facing:

We need to create an SD invoice which has both positive (normal sales) and negative (returns) line items.

The problem is we need to post the positive items on the customer account and the negative ones on the vendor account. This has to happen when the customer is also a vendor for our organization.

How can this be done, without going into MM documents, so only in SD ?

Thankyou in advance,

Cosmin
