Elimination of inter unit transactions

Hi group,

We have a lot of interunit billing and vouching transactions that are posted to the AR and AP modules.  I know that your suggestion will
probably be that we should avoid billing between units but since these transactions are mostly populated through interfaces from external systems, we have no choice but to record them.

Because of our various lines of business, some of these transactions stand for internal subcontracts between units and some others are part of the cost of material sold.

In both cases, the result is the same:  we must pay and cash them in their respective modules.
