Data source and Extract Structure

Question

Hi all,
I have a doubt on Data source and Extract Str,
when i used one info cube with some char and kf's
after i did extraction shall we change the extract strcuture prequently other wise better to use all the predefined extract strcuture hide in data source.
if i hide in datasource after extraction i want to use some of hide fields, so we can use it? if we can use how can we extract data for that specified hide fields to bw side.

Answer 1

If you wont to create the genaric data source at that time
you can create cube with some char and kf.
after extraction you wont to modify the structure ? if you mofify
the structure then replicate the data source and delete the data
and upload the data from r/3 to bw.its not correct way every time modifying the
structure.if you put hide means that fields are not coming to
bw side.if put modify the hide field ,first goto rsa6 edit data source
remove the hide check box and save after come to bw replicate the data source
delete the data and load the data (if you wont full data for hide field)
if you dont load full load means only available upto data only what ever field you modify the
hide to unhide,
