18.2 ALV overview

ALV (ABAP List Viewer) displays tables with sorting, filtering, totals, layouts, and Excel export for free.

REUSE_ALV_GRID_DISPLAY / _LIST_DISPLAY Function modules, field catalog Legacy, still common OO, needs a screen + container Editable grids, complex dialogs CL_SALV_TABLE (SALV object model) OO, simple, no field catalog needed Recommended for read-only reports ALV with Integrated Data Access on HANA Huge data sets, paging pushed to DB Fiori elements list report Browser, RAP/OData

18.3 REUSE_ALV_GRID_DISPLAY (legacy)

18.4 CL_SALV_TABLE (recommended)

Event handling (e.g. double-click):

18.5 ALV with IDA (HANA)

Only the visible rows are fetched; sorting, filtering, and aggregation run in the database.
