SAP Note 22812 - XXL: Key columns are missing

Symptom:

When a list object is exported to XXL, some of the key columns appear to be missing.

Cause and prerequisites

The key columns are in fact not missing. Whenever the full key would occupy too much space on the screen, the XXL Listviewer automatically scrolls out some key columns when first displaying the list object.

Solution
The invisible screen columns can be scrolled back in using either the menu ( View -> Fix Window ) or the corresponding icon (the 3rd one from the left). You have to activate a cell in any key column first. Depending on which column you choose, the Listviewer will scroll the key columns either to the left or to the right.
