Group and Columnar Section Event Flow
The system processes group and columnar sections alike because they both write to the output after each record is read. This processing is unlike tabular section processing, which writes to the output only when a level break is encountered. The output is determined by the data selection and data sequencing defined in the section.
This diagram illustrates the typical event flow for group and columnar sections:
