To add a category, follow the steps below:
To add a view element, take either of the following two ways:
next to the Mapping Name text field to specify the mapping field of the view element.By default, the display name is the same as the mapping name. You can change it according to your requirements. The display name must be unique at current level.
Tip: If you want to add a detail object to a group or an aggregation object, you can right-click the group/aggregation object, select Add Detail from the shortcut menu and then edit the detail object as required.
In the Business View Editor window, drag a table, DBField, formula, or summary from the Resource Objects panel to the business view or a category. Then, all DBFields in the table, the DBField, formula, or summary will be added as view element into the business view or the category you drop it into. JReport will determine the type automatically which may not meet your requirements. You can edit the view element to change it to the required type. Moreover, you can drag a DBField of data type other than Integer and Date or a formula to a group or aggregation object to add it as a detail object.
