plzz help me giving all the possible ways with explanation to do the following :------
i dont want the database table to use regularly, so i created 3 internal tables from which i want to extract data & put those data in the main output table which is used in ALV.
the 3 internal tables are linked thru primary keys.....but want other fields to be extracted thru primary-foreign key relationship.
how should i bring the data from the the 3 internal tables into the output internal table ?
