Controlling Page Breaks with Multiple ON-BREAK Columns
When multiple columns have ON-BREAK, page breaks need careful planning. While having a page break within a group, you probably would not want to have one within a record.
You can prevent page breaks within a record by following four simple rules:
Place ON-BREAK columns ahead of other columns in the select paragraph.
Place the lower-level ON-BREAK columns ahead of the higher-level ON-BREAK columns in the select paragraph.
Use the same line positions for all ON-BREAK columns.
Avoid using WRAP and ON-BREAK together on one column.
