In Read table can I use not equal to? Normally by comparing two internal table, we using like
loop it_tab1 into wa_table1 read table it_table2 with key col1 eq 'one'
In the above statement in place of eq can I use <>
No, you can use Not Equal To (NE) in Read table, instead, you can loop with Where Clause and Exit after a single record is read because you will get only single entry of your key fetched with the read statement.
Note: You will have to sort the table according to your key so that you get all those entries which satisfy your need.
SORT ........... LOOP at it_itab1 into wa_itable1 where field NE field. Write you your code here. EXIT. //since only one record of your keys will be fetched therefore write an exit after your code. ENDLOOP
