To add a new record, simply navigate to the tab and click the "Add New Service/Repair/Upgrade Record" button and you will be prompted to input the details of the record.
If you have supplies set up, you can click the "Choose Supplies" link under the Cost field, and a dialog will prompt you to select the supplies and quantity of each supplies you wish to requisition for this record.
Once you have selected the supplies, the Cost field will automatically update to reflect the costs of the supplies you have selected based on the quantity of each supply. Note that at this point, before the record is created, the supply is not requisitioned yet and you can still edit the selected supplies/quantities.
