Logic issue with Internal Table

Question

Hi All,
I have an internal table with following structure.
Name of Internal table: ITAB
Fields:   userid      login date     number
Values:  abc         01012008    
             abc         02012008
             abc         02012008
             abc         03012008
Now i should store the value for the field itab-number, based on the ita-logindate.
If the field logindate is having same date for 2 times (for the user 'abc'),
the field itab-number should have the value as '2' .
Basically i want to display a report to show how many times a user has logged into SAP system for a given date.......
How to incorporate this logic?
Regards

Hi,
Use the below logic.
data: begin of itab1 occurs 0,
       uid  like sy-uname,
       date like sy-datum,
      end of itab1.
data: begin of itab2 occurs 0,
       uid  like sy-uname,
       date like sy-datum,
       count type i,
      end of itab2.
data v_count type i.
start-of-selection.
itab1-uid = 'abc'.
itab1-date = '20080101'.
append itab1.
itab1-uid = 'abc'.
itab1-date = '20080102'.
append itab1.
itab1-uid = 'abc'.
itab1-date = '20080102'.
append itab1.
itab1-uid = 'abc'.
itab1-date = '20080103'.
append itab1.
itab1-uid = 'abc'.
itab1-date = '20080104'.
append itab1.
sort itab1 by uid date.
loop at itab1.
v_count = v_count + 1.
at end of date.
itab2-uid = itab1-uid.
itab2-date = itab1-date.
itab2-count = v_count.
append itab2.
clear  v_count.
endat.
endloop.
