SUM and Percent

[jopo12345678]

Hello,

How to create table like this one below. Sum first and second value and than from each value get rate. Is there anybody who know code for this problem?

My data

date	Value	E	D
201612	82842	0	0
201612	621	0	1
201612	31595	1	0
201612	64	1	1

Want data

date	Value	E	D	Sum	Rate
201612	82842	0	0	83463	0,74%
201612	621	0	1
201612	31595	1	0	31659	0,20%
201612	64	1	1

data want;
merge
  have
  have (firstobs=2 rename=(e=_e d=_d date=_date value=_value))
;
if d = 0 and _date = date and _e = e
then do;
  sum = value + _value;
  rate = _value / sum;
end;
format rate percent7.2;
keep date value e d sum rate;
run;

Edit: added a closing bracket in the merge statement, to correct a syntax error.

This is result of this code...it doesnt work properly.

date	Value	E	D	Sum	Rate
201612	621	0	0	1242	50.0%
201612	31595	0	1	.	.
201612	64	1	0	128	50.0%
201612	64	1	1	.	.

data have;
input date $ value e d;
cards;
201612 82842 0 0
201612 621 0 1
201612 31595 1 0
201612 64 1 1
;
run;

data want;
merge
  have
  have (firstobs=2 rename=(e=_e d=_d date=_date value=_value))
;
if d = 0 and _date = date and _e = e
then do;
  sum = value + _value;
  rate = _value / sum;
end;
format rate percent7.2;
keep date value e d sum rate;
run;

proc print data=want noobs;
run;

Result:

 date     value    e    d     sum        rate

201612    82842    0    0    83463     0.74% 
201612      621    0    1        .      .    
201612    31595    1    0    31659     0.20% 
201612       64    1    1        .      .
