Please Complete the Split Tender Transaction

A split transaction lets you run multiple tenders to finish a transaction.

When a split transaction is started it has to be finished . So if a user selects split tender and runs half of the transaction in cash and tries to go back to the sale transaction screen, it will error out until the open split transaction is completed. 

If the transaction was made in error it will need to still be finished, but a user can run a return to reverse any transaction
