Diagnosis
The price differences were only introduced in billing. As a consequenceeach batch should be considered as a separate line in the Nota Fiscalto be able to handle returns correctly. As the prices were equal untilbilling, the batches are summarized and the prices cannot be changed inbilling.

Procedure
If the prices must be different for the individual batches, then thisdifferentiation must already be made during order registration (Sales).When Goods Issue has been made, a Bill must be generated. The Bill mustthen be reversed with a return and a new order must be created with theindividual batches with price differences.
