Is that possible to delete invoiced sales orders related to WMS. If You try to delet invoiced sales order manually, there's a message saying:
Sales orders cannot be deleted while dependent Order lines exist. Delete dependent Order lines and try again.
If You try to delete order lines, then following message appears:
Cannot delete - SalesLine has work associated to it.
So it appears, that if client uses WMS, then there's no option to delete invoiced sales order. Is that true ?
