ALV (ABAP List Viewer) vs. Normal ABAP Report

Notes

Introduction. ALV – ABAP List Viewer (4.6B) ALV Grid Control vs. ALV List Advantages

o No huge selection screens – use filters – (moderate use!)o Minimal maintenance if done properly

Extract lots of data Work with user on possible data requirements Setup variants together with the user

o User-friendly functionality (Download to Excel etc.)o Non-Statico It is not an updating tool!

Workingso Grid / Report

Moving of columns Total / Sub Total (Breaks) / Hide Columns Sort / Filter / Blank Control Breaks not on List Hotspots Multiple lines report (ALV List only) Buttons Variants (User / Set as default / “/GENERAL”) When it dump (Flush / CNTL-ERROR) Differences between 4.6B & 4.6C

Helpo Users & ABAPers

SAP Library ► Search Tab ► Enter “ALV Grid” ► Select “ABAP List Viewer (ALV) Grid Control (Getting Started)”

o ABAPers SAP Library ► Index Tab ► Enter “ALV” ► Select “ALV Grid

Control” ► Select “BC – ALV Grid Control” (Hotspot on right-hand panel)

ABAP ALV Report. Use Function Modules Pass parameters using fields, structures & tables Use dynamic events GUI status Logo in Grid – not printed or shown on print preview!

Pitfalls, Disadvantages & Tips. Dumps – Messages are not to useful

o Flush – CL_GUI_… (4.6B / C with latest service packs)o Discuss Application Server vs. Presentation Servero Check ITAB-fieldname and Initialize_ALV (Incorrect fieldnames)

Memory block read – Shows a page of icons

Report variant (Transportable???) Report cut-off after 255 columns Multiple lines not downloadable to Excel Statistics pages will have to be reported with separate button Zebra lines on report (not on grid) Colour of lines / columns – Use ‘soft’ colours (Different in 4.6C ???) SAP standard ALV reports – Be careful

o Not “populating” all fields of “ITAB”o Looping through selection more than once – Some advantages

Discuss not using huge selection screens Page number 0 on Grid (and after using list) Total number of records – create count field in ITAB Dialog programs – Heading only 80 columns

Additional Stuff. Logos Using ALV Grid in WANs Full Excel capabilities in SAP Using Graphs (minimal effort)

ABAP ALV Dialog Program. Use objects
