Prior Label

The prior label name of group label or table label.

If you set Prior label for a label, then the label will not be grouped if the prior label is not grouped.

Since Prior Label is only used for grouping, it is only available for a label whose Data Type property is "Group" and a table label whose Grouping property is "True".

Prior label can be set using the group label wizard for group label and the grouping setting wizard for table label as well as the properties window.

Prior label is not available for mutual reference or circular reference between labels.

If not set, it is displayed as "Root" by default.

To show a priority arrow between group labels, set the Show Group Link property of the band to "True".

In the example below, the first column is the prior label of the second column that shows the country.

When set the prior label, split label if its prior label values are different. If not set the prior label, merge labels with same value. In this example, with prior label, group labels with the same value of "USA" are merged and group labels are split by prior value of 1, 2, 4, and 5. With no prior label, group labels with the same value of "USA" are merged unconditionally.
