Hi

I have a requirement to remove duplicates from two different file if it has duplicates in two different files not in the same. If the duplicates are in the same file then the duplicates should not be removed.

For Example:

File 1 has

AAAAAAA,1234
ZZZZZZZ,3452

File 2 has

AAAAAAA,1234
BBBBBBB,2345
BBBBBBB,2345
CCCCCC,5678

File 3 should have

BBBBBBB,2345
BBBBBBB,2345
CCCCCC,5678
ZZZZZZZ,3452

(order is not important)

Can anyone please guide to acheive this via JCL sorts? I need to consider both the fields in the sort separated by comma.

This can be achieved using JOINKEYS.

Code:

//SYSIN    DD *                                         
  OPTION  COPY                                           
  JOINKEYS FILE=F1,FIELDS=(1,12,A)                       
  JOINKEYS FILE=F2,FIELDS=(1,12,A)                       
  JOIN UNPAIRED,F1,F2,ONLY                               
  REFORMAT FIELDS=(F1:1,12,F2:1,12)                     
  OUTREC IFTHEN=(WHEN=INIT,BUILD=(1,24)),               
         IFTHEN=(WHEN=(1,1,CH,EQ,C' '),BUILD=(1:13,12)) 
  OUTFIL FNAMES=SORTOUT,REMOVECC,BUILD=(1,12)           
//*                                                     


Output

Code:

BBBBBBB,2345
BBBBBBB,2345
CCCCCCC,5678
ZZZZZZZ,3452

Here are two more ways to do it with DFSORT's JOINKEYS (I assumed the input files have FB/80):

Code:

//S1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//IN1 DD DSN=... input file1 (FB/80)
//IN2 DD DSN=... input file2 (FB/80)
//SORTOUT DD DSN=...  output file (FB/80)
//SYSIN DD *
  JOINKEYS F1=IN1,FIELDS=(1,15,A)
  JOINKEYS F2=IN2,FIELDS=(1,15,A)
  JOIN UNPAIRED,F1,F2,ONLY
  REFORMAT FIELDS=(F1:1,80,F2:1,80,?)
  OPTION COPY
  INREC IFTHEN=(WHEN=(161,1,CH,EQ,C'1'),BUILD=(1,80)),
        IFTHEN=(WHEN=NONE,BUILD=(81,80))
/*


Code:

//S2 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//IN1 DD DSN=... input file1 (FB/80)
//IN2 DD DSN=... input file2 (FB/80)
//SORTOUT DD DSN=...  output file (FB/80)
//SYSIN DD *
  JOINKEYS F1=IN1,FIELDS=(1,15,A)
  JOINKEYS F2=IN2,FIELDS=(1,15,A)
  JOIN UNPAIRED,F1,F2,ONLY
  OPTION COPY
  OUTFIL VTOF,BUILD=(5,80)
