I'm not able to void a Cash Sale due to this error - "This record cannot be deleted, because it is referred to by other records". I obviously can't delete the attached Sales Order record. Has anyone been able to get around this? Thanks,

What does the Dependent Transactions link show. I wonder if there is a Make Deposit transaction. I don’t understand why a SO would be dependent. Any returns associated?

Any Cash Refunds?

The only associated record I found is the Sales Order.
