Hi,

It is used for all entries selection.....it checks whether there is any values is there any value or not.

if it_equz is not initial.
SELECT iloan
          tplnr
          msgrp
         INTO CORRESPONDING FIELDS OF TABLE it_iloa
          FROM iloa
          FOR ALL ENTRIES IN it_equz
          WHERE iloan = it_equz-iloan.
endif.

it checks whether itab is filled, where itab probably an internal table is.

Hi....

It is that if your internal table does not contain any values ... then do the proceed with the actions or else if internal table has the value the condition wont do anything.....

Hi Tanisha,

" if not itab is initial."

is used to check wheather the contnent of an internal table named itab is empty or not. Generaly, we use it after an operation to fill the itab and before working with the internal table.

In case of SELECT statement if we use FOR ALL ENTRIES, this checking is a must. Otherwise, if the internal table is entry the all the data of the data table/s in the SELECT query will be fetched.

         name1 type kna1-name1,
         ort01 type kna1-ort01,
         land1 type kna1-land1,
        end of ty_itab.

data : it_itab type table of ty_itab,
         wa_itab type ty_itab.

select-options : S_kunnr for kna1-kunnr.

select kunnr
          name1
          ort01
          land1 from kna1 into table it_itab where kunnr in s_kunnr.

" to check whether it_itab has records 
if IT_itab is not initial.
loop at it_itab into wA_itab.
write statemetns
'

If not Itab is initial.......

It indiactes go to further process if the Internal table contains records.

it will reduce the process time and increases the performance of the program.

Checking "If not Itab is initial' gains most importance if subsequently you are using the same table in 'For all entries'.

Else all records are fetched !! Hope it helps.

Hi,

'if not itab is initial' checks weather the itab filled with data or not.

For Example.

if not itab is initial.

Message 'Itab contains data' type 'S'.

else.

Message 'No data found' type 'E'.

endif.
