Diagnosis
The billing type could not be determined for the specified transaction.
This is caused by incorrect Customizing:

• In the case of order-related billing, the billing type is determined
from the order type.

• In the case of deliveries with reference to an order, the billing type
is also determined from the order type.

• In the case of deliveries without reference to an order, the billing
type is determined using the default order type of the deliery notetype.

• In cases where billing is created using the general billing interface,
the billing type is determined using the order type transferred in theinterface, as long as it was not transferred directly in the interface.
