A group left report (also called a break report) contains multiple groups in its data model, dividing the rows of a table based on a common value in one of the columns. Use this type of report to restrict a column from repeating the same value several times while values of related columns change. The data model for group above and group left reports is the same, but the layouts differ; group above reports display the master information at the top while group left reports display break columns (or break group) to the side.
For detailed examples of building various group left reports, see the following
