Capturing Custom Data
Once you have added fields and assigned them to check-in types at a location, they will be ready to gather the details you want.
Do a check-in of that type at the location, and you will see the data fields you added.
Record data for each of the fields, and complete the check-in.
This data will become part of the item's history which you can see by looking at the item and clicking its history. (You can find an item by searching for it, or clicking through Item Types.)
