Can you help me

Thanks
Shyamsaravan

For the above requirement is to do with JCL SORT

It will run on daily by scheduler except Saturday and sunday

shyamsaravan,

The following DFSORT JCL will give you the desired results.

Thanks Skolusu
Thank you for the quick reply,,but the above code is not fulfil my requirement,,It is just copied all input records to the o/p GDG file,the only change reflected is'99TRailer 0000002 0000001 000001' It is also not...ok,,I explain in detail

I need to fetch the only those records from the current version of GDG input file..The i/p file created every day except Sat and SUN,So the header date and compare field date will vary,,I am giving the input file created on 11th May 2010

00HEADER 11/05/10
0311RON2010051000009628470678300000000000000 --COMPARE FIELD IS '0311RON20100510'--Pos 1-15(date pos 8-15)
0311EUR2010051000013022594400100000000000000 --COMPARE FIELD IS '0311EUR20100510'

0310RON2010051000003039290848100000000000000 --COMPARE FIELD IS '0310RON20100510'
99TRAILER

Note: in Compare field 0311RON20100510---20100510 is the previous date of HEADER DATE
The trailer has count of o/p records and 1 header record,1 trailer record and total no of records(incl of header and trailer)
for this case no of records 000004,header record 000001,trailer record 000001 total records 000006
99TRAILER 000002 000001 000001 000006---IT IS THE FORMAT

One more thing,,If we used for Monday created GDG input file means it doesnt have previous day record..for this case we go for friday date record(that is 2 day in advance)..for example SEE THE FILE Header date is 10th may2010(Monday),but it has friday date record(20100507) at the position 8-15

Shyamsaravan,

You try to complicate a simple request. From what I understood till now is that

1. Header record will have the current day date (can be monday thru friday)
2. The detail records will have the prior day records.

If that is true then use the following DFSORT JCL.



PS: If your header date has anything other than current date and if you want to do the comparison, then you need to write a program to perform the date arithmetic on any given date as sort products do not have capability of performing date arithmetic on any date.

Thanks again;

1.Header date will not be the current date,but the new JCl will not run the current header date,,It may run any date,,
2.You are right..The detail record will have the Prior day record .(If the priod day record is not available for the time of comparision,we
should fetch for two day prior record -For Ex..Header date is 10/05/10,this file doent have a prior days records,bcoz prior days are SUNDAY
and SATURDAY,so we have to fetch FRIDAY(07/05/10) detail record.
3.Trailer record should have a no.of detail record,No.of Header record,No.of Trailer record and Total no.of records
like 99TRAILER 0004 0001 0001 0006--This is for the above o/p file counts,,,,4 detail record,1 head rec,1Trail rec,6--total rec

4.Comparision key is like these only 0310EUR+priordate,0310RON+priordate,0311EUR+priordate and 0311RON+priordate

For Example Header date is 11/05/10 is the comparision keys will be the

0310EUR20100510
0310RON20100510
0311EUR20100510
0311RON20100510
for eg Header date is 10/05/10 means ,the comparision keys will be the

0310EUR20100507
0310RON20100507
0311EUR20100507
0311RON20100507--two day prior(bcoz 20100509 is SUNDAY,20100508 is Saturday)


So search the prior day with that comparisonkey,if the record idexist move to Output GDG,If not search the two day prior with comparioson key,if exist move to O/P .Please dont mind in current date

Please let me know,if any

Kindly;
Shyamsaravan

Shyamsaravan,

Did you read this in my last post?

Yes Kolusu;

I read the the lat post...Just convert(Reformat) the header date format(dd/mm/yy) to Record date format(YYYYMMDD) and check the prior day of header date Record in detail records with additional searck key of '0310EUR','310RON','0311EUR','0311RON', if is available,do write that selected records to output record,if it is not available means check two days prior day record in detail record and write to o/p file.
Trailer record should have a count of Detail record,count of Header record,cont of Trailer record,and count total records(incl of Head,TRial,and Detail record cont)..

If the header date is 14/05/10 means
|------date format is YYYYMMDD
The search key are, 0310EUR20100513,,0310RON20100513,,0311EUR20100513,,0311RON20100513

If the header date is 17/05/10 means

The search key are, 0310EUR20100514,,0310RON20100514,,0311EUR20100514,,0311RON20100514

Please help me;
