tree in table or table popin
I would like to create a webdynpro java to export output of transaction MB51, this transaction use hierarchical ALV..
In this alv I have 2 table: header table with "material" "Description" "Plant" ecc
and item "son" table with "doc. number", "posting date", quantity ecc.
How can I recreate this structure with table java?
in WDJ I never used tree or table popin and so I dont' know their feature fine..
Thanks for any sugges!
