Completion code validation required is set as a Practice Default to be used as a security measure when lodging returns. Refer to Defaults.
In practices using this security feature when attempting to output a return for lodgment, the Completion Code Validation window displays. The user must type the correct completion code to allow the lodgment process to continue.
Each return or form has a separate completion code allocated to the form by the program when the user selects to mark the return as Complete.
