Hello,

I am just wondering if the below requirement can be done through Syncsort (I have SYNCSORT FOR Z/OS 1.2.2.3N in my shop).

Input file - LRECL - 150, RECFM - FB
Code:

Field      Pos       Data Type   
-----   ---      ----------
Acct No    1-8       Char ( 8 )
Activity   9-12       Char ( 4 )
Date   23-30(YYYYMMDD)    Char ( 8 )

Sort criteria :

The Acct No and Date would be ascending order.
Also, the file should be sorted in such a way that for every unique combination of Acct No and Date, the Activity should appear in the below mentioned order.
On a single day, any one or more than one of the Activity may appear for one Acct No in th e input file. There are several other Activity codes, which should appear in ascending order.
Code:
 
Activity Sequence in output
--------------------------------
 0100
 3018
 3052
 3061
 3060
 3051
 3062

Example :

Input
Code:

-----
Pos 1-8      Pos 9-12      Pos 23-30
-------      --------      ---------
18856735      3062         20070127
18856735      3051         20070127
18856735      3060         20070127
17734567      3018         20070128
17734567      0100         20070128
19923218      3061         20070129
19923218      3052         20070129
19923218      3060         20070129

Output
Code:

-------
Pos 1-8      Pos 9-12      Pos 23-30
-------      --------      ---------
18856735      3060         20070127
18856735      3051         20070127
18856735      3062         20070127
17734567      0100         20070128
17734567      3018         20070128
19923218      3052         20070129
19923218      3061         20070129
19923218      3060         20070129

Could you please let me know how this can be done through Syncsort,
Thanks!

Pranabesh,

Your Output does NOT match the specs. If you want ascending acctno and date seq the acct no 17734567 will be the first record instead of 18856735. Do you want the output to be sorted first on date and then on the Acct no?

Any way try these untested sort control cards which will give you the results. For all the possible activity sequence assign a variable at the end(151) and sort on it along with acctno and date to get the records in the sequence. While writing out to the output we remove the assigned sequence

Code:

//SYSIN    DD *                             
  SORT FIELDS=(001,08,CH,A,   $ ACCT-NO     
               023,08,CH,A,   $ DATE         
               151,05,CH,A)   $ SEQUENCE     
                                             
  INREC IFTHEN=(WHEN=(09,04,CH,EQ,C'0100'), 
       OVERLAY=(151:C'00001')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3018'), 
       OVERLAY=(151:C'00002')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3052'), 
       OVERLAY=(151:C'00003')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3060'), 
       OVERLAY=(151:C'00004')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3051'), 
       OVERLAY=(151:C'00005')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3062'), 
       OVERLAY=(151:C'00006'))               
                                             
  OUTREC FIELDS=(001,150)                   
/*

Sorry Kolusu, while writing the output example I mentioned the wrong order by mistake. You are right, and the solution worked great!!
Thanks a lot, Kolusu!

Hi Kolusu,

One more question. There are several other Activity types e.g. 1439, 6500,0017, 5001.
Can you please let me know how the sort card be changed so that all other Activity types would come after the Activity types I have provided initially, i.e. without overlaying with unique characters for each of the other Activity types,

Thanks!

Just assign a higher value for all the other activities . Check for when=none

try these control cards

Code:

//SYSIN    DD *                             
  SORT FIELDS=(001,08,CH,A,   $ ACCT-NO     
               023,08,CH,A,   $ DATE         
               151,05,CH,A)   $ SEQUENCE     
                                             
  INREC IFTHEN=(WHEN=(09,04,CH,EQ,C'0100'), 
       OVERLAY=(151:C'00001')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3018'), 
       OVERLAY=(151:C'00002')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3052'), 
       OVERLAY=(151:C'00003')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3060'), 
       OVERLAY=(151:C'00004')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3051'), 
       OVERLAY=(151:C'00005')),             
        IFTHEN=(WHEN=(09,04,CH,EQ,C'3062'), 
       OVERLAY=(151:C'00006')),               
        IFTHEN=(WHEN=NONE, 
       OVERLAY=(151:C'10000'))
                                         
  OUTREC FIELDS=(001,150)                   
/*   


Hope this helps...

Cheers

Kolusu
