**Sorry guys for above wrong code which I posted, You can **use this code with 100 % result****
tables : ywt_student, ywt_result.
data : begin OF itab OCCURS 0, "structure from 2 tables
usn like ywt_student-usn,
name like ywt_student-name,
dob like ywt_student-dob,
cls like ywt_result-class,
marks like ywt_result-marks,
end of itab.
**"selecing values from 2 tables*****
select ywt_student~usn name dob class marks
INTO TABLE itab
from ywt_student INNER JOIN ywt_result on ywt_student~usn = ywt_result~usn.
**Sorting for testing Perpose*****
sort itab by cls ASCENDING marks DESCENDING.
LOOP AT itab.
on CHANGE OF itab-cls.
skip.
ENDon.
WRITE :/ itab-usn, itab-name, itab-dob, itab-cls, itab-marks.
ENDLOOP.
skip 2.
***Actual Logic of Requirement***
data : m LIKE ywt_result-marks.
data : count TYPE i value 0.
CLEAR itab.
sort itab by cls ASCENDING marks DESCENDING.
CLEAR itab.
LOOP AT itab.
m = itab-marks.
on CHANGE OF itab-cls.
skip 2.
count = 0.
ENDon.
AT NEW cls.
itab-marks = m.
count = count + 1.
IF count LE 10.
WRITE :/ itab-usn, itab-name, itab-dob, itab-cls, itab-marks.
CLEAR itab.
ENDIF.
ENDAT.
ENDLOOP.
