ALV Hierarchical Report

We can prepare a report which can display hierarchical data. There will be a header record and hierarchically there will be item wise record. This can be done by a function module REUSE_ALV_HIERSEQ_LIST_DISPLAY.

Prerequisite of this Function Module:

·         This module outputs two internal tables as a formatted hierarchical-sequential list.

·         It needs an internal table containing the set of header information to be output.

·         It needs an internal table containing the set of item information to be output.

·         It needs a layout structure.

·         It needs a field catalog (Header + Item) in the form of an internal table. The field catalog describes the fields to be output in the list.
