您看起来像是stackoverflow的新用户。欢迎你的问题被否决至少有三个原因:

1) It's not really clear what you want from your description of the problem and the data
   you're providing

2) You haven't shown any attempts at what you've tried

3) Providing your data as a picture is not great.  It's most helpful if you're going
   to provide data to provide it so it's easy for others to consume in their program.  
   After all, you're asking for our help make it easier for us to help you.  If You 
   included something like the following we just have to copy and paste to create your
   dataset to work with:

    DATA test;    
    INPUT ID YEAR EXEC SUM;
       DATALINES;
    1573 1997 50 1080
    1581 1997 51  300
    1598 1996 54   80
    1598 1998 54   80
    1598 1999 54   80
    1602 1996 55  112.6
    1602 1997 55  335.965
       ;
    RUN;

下面的话可能会告诉你你想要什么,但这只是猜测,因为我不确定这是否真的是你想要的:

proc sql no print;
     create table testout as
            select *,count(*) as cnt
      from test
            group by sum
                  having cnt > 1;
quit;

input ID YEAR EXEC SUM
    1573 1997 50 1080 //
    1581 1997 51  300 //
    1598 1996 54   80 //
    1598 1998 54   80 //
    1598 1999 54   80 //
    1602 1996 55  112.6 //
    1602 1997 55  335.965 //
    1575 1997 50 1080 //
    1575 1998 51 1080 //
    1595 1996 54   80 //
    1595 1998 54   30 //
    1595 1999 54   80 //
    1605 1996 55  112.6 //
    1605 1997 55  335.965 //
end

bysort ID SUM: gen drop=cond(_N==1, 0,_n)
drop if drop==0

结果显示(根据我的数据):

   
    ID      YEAR   EXEC  SUM    drop    

1.  1575    1997    50  1080    1   
2.  1575    1998    51  1080    2   
3.  1595    1999    54  80      1   
4.  1595    1996    54  80      2   
5.  1598    1996    54  80      1   

6.  1598    1998    54  80      2   
7.  1598    1999    54  80      3
