How can I get Number of Lines from internal table?

Question

Hello at all,
i have in my Report a internal Table, which have many KUNNR.
For example the internal Table:
MANDT.......KUNNR......NAME.........FIRSTNAME........CITY
...040..........12345.........Owen............Michael........Liverpool
...040..........12345.........Owen............Michael........Liverpool
...040..........99999.......Johnson.......... Jeffrey........London
...040..........12345.........Owen............Michael........Liverpool
...040..........55555.......Hardley.......... Kingston.......Birmingham
I want to know, how many same KUNNR are existing in the internal Table?
In my example i need the result 3, because their is existing 3 times the Kunnr 12345 in the internal Table.
Have anyone an idea, how can I resolve this problem?

Answer 1

Hi,
1.Create two internal tables of same type and sort according to Kunnr then Delete the
adjusent duplicates by comparing KUNNR
2.Sort the table by KUNNR and use ON change of Concept in that Just increment the counter.
I am writing the sample logic here.
tables kna1.
data: t_kna1 type table of kna1,
         w_kunnr type kna1-kunnr,
         counter type i," Holds No.of KUNNRs in the T_kna1
         t_kna2 type table of kna1.
select * from kna1 into table kna1 up to 100 rows.
t_kna2[] = t_kna1[].
delete t_kna2 by kunnr.
delete adjusent duplicates from t_kna2 by comparing kunnr."1st Method
read table t_kna2 transporting no-fields.
counter = sy-tfill."1st Method
loop at t_kna1 into kna1."2nd Method
at first.
w_kunnr = kna1-kunnr .
counter = 1.
endat.
if w_kunnr ne kna1-kunnr.
counter = counter + 1.
endif.
endloop.
Note : Here I used a sample table KNA1 in this there are no Duplicates of KUNNR .
