Can I delete or unlink a fixture from a scheduled voyage without deleting the voyage?

No. Once a cargo fixture is linked to a voyage, it creates a permanent connection between the cargo and the voyage. This means the fixture cannot be unlinked or deleted independently of the voyage.

Additionally, the Opr Type of a voyage can only be changed from TCOV to TCTO if there is no fixture number associated with it. In all other cases, changing the Opr Type or removing the fixture requires deleting both the voyage and the fixture.
