Expand/Collapse button will provide an option to users to only see the Header List. By selecting the expand button, it will show both Header and detail List. By selecting the same button again it will collapse the list and gives only the header list.
Here is the code Snippet which provides the ADD-ON code. This ADD-ON code can be replaced with the relevent section from this code snippet in the base program. You can find the base program code snippet in the post SALV Hierarchical Table 1 : Simple table display. Adding code to base program is like adding the code correction from the OSS Note. Additionally, we will always include the default PF-status in all the code snippet.
UML diagram for the application would be like:
Code snippet to get the Expand / Collapse option in Hierarchical ALV.
This code will generate output like:
