Working with Lists
SAP List Viewer (ALV) for SAP GUI is a powerful tool used for displaying large data sets. Operations that are often used for optimizing the display or executing different standard calculation steps are already integrated into the list display and can be used in a uniform way.
However, since not all of the data records that are to be displayed have the same structure, there are essentially three different types of ALV lists that are described below.
The simple, two-dimensional table is the most common form of display. It can be integrated as a Fullscreen View or as a Grid View with further lists or other elements on a screen.
The tree structure can also be integrated as a Fullscreen View or as a Grid View with further lists or other elements on a screen.
The hierarchical-sequential list is based exclusively on the older SAP List Viewer for SAP GUI (Classic) technology.
There is a further variant of the simple, two-dimensional table (see above) also based on the classic technology. These two tools behave similiarly due to their common technical origin.
You can find documentation about working with hierarchical-sequential lists and the classic variant of the simeple, two-dimensional table in sectionSAP List Viewer für SAP GUI (Classic).
