Hi I have the data like below. I want to calculate the total with in the group without considering that corresponding value.

if you take G3: for t8 after removing t8 value then the group total is : 1250, like that i want all the combinations sum.

Is there any macro required here? can you please give some thoughts how can we proceed on this task. Thanks in advance.

data groups;

input group$ subg$ marks;

cards;

G1 t1 500

G1 t2 300

G1 t3 400

G1 t4 100

G2 t5 600

G2 t6 400

G2 t7 200

G3 t8 650

G3 t9 800

G3 t10 450

run;

i want output as:

Group	Sub G	Marks	total
G1	t1	500	800
G1	t2	300	1000
G1	t3	400	900
G1	t4	100	1200
G2	t5	600	600
G2	t6	400	800
G2	t7	200	1000
G3	t8	650	1250
G3	t9	800	1100
G3	t10	450	1450

Use a SQL summation and then subtract the row value.

data groups;

input group$ subg$ marks;

cards;

G1 t1 500

G1 t2 300

G1 t3 400

G1 t4 100

G2 t5 600

G2 t6 400

G2 t7 200

G3 t8 650

G3 t9 800

G3 t10 450

run;

proc sql;

create table want as

select group, subg, marks, sum(marks)-marks as total

from groups

group by group

order by group, subg;

quit;

proc print data=want;

run;
