Hi All,
If we use FOR ALL ENTRIES, first internal table should
have at least one record ( ie, it should not initial ).The
data will fetch from database based on second select
statement,irrespective of first internal table records ,
because first internal table is empty.
It is best practice to use IF NOT I_TAB1[] IS INITIAL.
Because we use FOR ALL ENTRIES statement to avoid the
duplicates entries.
