SK2007,

The following DFSORT/ICETOOL JCL will give you the desired results

Code:

//STEP0100 EXEC PGM=ICETOOL                                         
//TOOLMSG  DD SYSOUT=*                                             
//DFSMSG   DD SYSOUT=*

Hi Kolusu,

Thanks for your help. It is working as expected.
But I need one more condition to be considered to sort the records.
In addition to the conditions mentioned, I want to keep records when the date is greater than todays date.
For ex:
Quote:

----+----1----+----2----+----3----+----4----+----5----+----6
123456789 NAME1 45.78 2009-01-01 AC 50.00 1
123456789 NAME1 45.78 2009-01-01 AC 50.00 2
123456999 NAME2 55.78 2009-10-01 AC 40.00 1
123456999 NAME2 55.78 2009-10-01 AC 40.00 2
123456122 NAME3 30.00 2007-10-01 AC 30.00 1
123456122 NAME3 30.00 2008-10-01 AC 30.00 1
123456233 NAME4 10.00 2007-10-01 AC 20.00 1
123456233 NAME4 10.00 2008-10-01 AC 20.00 1
123456233 NAME4 10.00 2009-10-01 AC 20.00 2
123456002 NAMEx 10.00 2010-02-01 AC 20.00 1
123456002 NAMEx 16.22 2010-02-10 AC 45.00 1
123456002 NAMEx 14.69 2010-03-01 AC 20.00 2


The output should be

Quote:

123456789 NAME1 45.11 2009-01-01 AC 50.00 1
123456789 NAME1 45.13 2009-01-01 AC 50.00 2
123456999 NAME2 55.01 2009-10-01 AC 40.00 1
123456999 NAME2 55.99 2009-10-01 AC 40.00 2
123456122 NAME3 30.00 2007-10-01 AC 30.00 1
123456233 NAME4 10.11 2007-10-01 AC 20.00 1
123456233 NAME4 10.00 2009-10-01 AC 20.00 2
123456002 NAMEx 10.00 2010-02-01 AC 20.00 1
123456002 NAMEx 16.22 2010-02-10 AC 45.00 1

SK2007,

I noticed that my earlier control cards had a typo. I corrected it , it gives the desired results the data would be sorted in the Mbr-id ascending. As for the latest requirement the follwing DFSORT/ICETOOL JCL will give the desired results

Code:

//STEP0200 EXEC PGM=ICETOOL                                           
//TOOLMSG  DD SYSOUT=*                                                 
//DFSMSG   DD SYSOUT=*                                                 
//IN       DD *
