Internal tables open automatically in the ABAP Internal Table view. This view lets you work comfortably with the rows of an internal table.
You can quickly scroll through long tables and re-arrange table columns for better display with drag-and-drop.
Procedure
- In the Variables view of the Debug perspective, double-click the node
for the internal table in question.
The internal table is automatically opened in the ABAP Internal Table view.
- Alternatively, you can also type an internal table name directly into the view or select an internal table in the code that you are debugging.
