if your itab contained

NUM

now sort the itab descending

data : l_grnum type I.
sort itab by NUM descending.
read table itab index 1.
if sy-subrc = 0.
l_grnum = itab-NUM.
endif.

Hi,

Take a variable in Max....Then compare each value with max.....If the value is greater than the variable , then store the value in max.....Do this for all values..

Loop.

If value in list > max.

Max = value currently in list.

Endif.

Endloop.

Thanks,

Aditya.

Four differently named variables... no-one said anything about internal tables.

If a gt b.
  biggest = a.
ELSE.
  biggest = b.
ENDIF.

IF biggest gt c.
  biggest = c.
ENDIF.

IF biggest gt d.
  biggest = d.
ENDIF.

biggest = a.

if a < b.

biggest = b.

elseif a < c.

biggest = c.

elseif a < d.

biggest = d.

endif.

Hi,

PARAMETERS : a TYPE n,

b TYPE n,

c TYPE n,

d TYPE n.

DATA : e TYPE n,

f TYPE n.

IF a > b.

e = a.

IF c > d.

f = c.

ELSE.

f = d.

ENDIF.

ELSE.

e = b.

IF c > d.

f = c.

ELSE.

f = d.

ENDIF.

IF e > f.

WRITE : /1 e.

ELSE.

WRITE : /1 f.

ENDIF.

oops. But mine was embedded in code tags, so easier to read

matt

should read more carefully to see that the answer is wrong. Thanks Eric!

no, it is completely wrong...

biggest = a.

biggest = b.

elseif a < c.

biggest = c.

elseif a < d.

biggest = d.

endif.

if the bold part is true, the value of c and d won't even be considered!

best part is to make a internal table

add all items to it

sort it

if not then usinf nested if endif will solve your purpose

i think both of the solutions have ben mentioned above in youir replies

if your query is answered please mark it answered

and do reward others

thank you

Thanks alot & Sorry Eric, Matt, Gopi....

I too realized now....

I will change my logic...

if a < b or a < c or a < d.

if b < c or b < d.

if c < d.

biggest = d.

else.

biggest = c.

endif.

else.

biggest = b.

endif.

else.

biggest = a.

endif.

biggest = a.

if biggest < b.

biggest = b.

endif.

if biggest < c.

biggest = c.

endif.

if biggest < d.

biggest = d.

endif.

Hi salma,

1. This is one way.

Data : max type i.

*----

Put first value

max = a.

*----

Then compare with other three varibles

if b > max.

max = b.

endif.

if c > max.

max = c.

endif.

if d > max.

max = d.

endif.

regards,

amit m.
