If you have enabled the function to have a mixed cost status in single jobs (where you can opt-out from charging single costs) you will see the option to 'select costs' when creating a charging batch file.
Before creating a charging batch file, please press Select Cost. This is to check if a batch is indeed required (if there is at least one chargeable cost) and to ensure you are happy with with costs are being charged. When you have checked, please select Create new batch.
Costs with a line through will be included in a separate batch file. Please review and create the batch as doing so will lock the included jobs.
