Data Grid Summaries
This component is used for adding more summaries fields.
StoreReport uses "#" in front of field name to distinguish summary field. It can be any number field from Skubana data. It can also be any custom field that you have added. When you add new summary field it will be added to the end of the Data Grid Fields list. From there you can drag to the front and place between other summary fields, and hit Refresh Data Grid button.
Be sure to add only line item fields.
