Good day, I'd appreciate some help to accomplish the following.
There's a sequential dataset, RECFM=FB.
Each record has an Acc-no and Job-no values. There could be multiple records with the same Acc-no but different Job-no.
Job-no's within a single account are always unique.
Record layout:
Acc-no x(08).
Name x(24).
Address x(34).
Job-no x(04).
Task:
Need to identify if there's at least ONE duplicate Job-no accross different accounts, and if there is, calculate total of Job-no within each of those accounts, to keep the one with a highest total count to an Output, and drop the others with lower totals. If totals within an identified bundle happened to be identical, keep one of those, regardless of its place, and drop the others. Totals can go from 1 up to 999.
Also store all non-matching by Acc-no/Job-no records to an Output.

ramy2016,
your requirement does NOT match with the output you show.
Why isn't Acc-no 00000100 not picked up? Same is the case with 00000400 Both of them have duplicates
Code:
Acc-No Name Address Job-no
00000100 1111
00000100 2222
00000400 3333
00000400 4444
00000400 6666

kolusu,
Acc 100 matched to Acc 300 through the Job-no 2222, but since Acc 300 had higher total of Job-no's, 4 vs 2, the Acc 100 got dropped. And the same goes for the Acc 400 which had matched to Acc 300 through at least one Job-no 333, but since Acc 300 had higher total of Job-no's, 4 vs 3, the Acc 400 didn't make it to an Output neither.

ramy2016,
Unfortunately achieving this using DFSORT would require more than 3 passes of data. Also the logic gets trickier if more than 1 duplicate job number matched with an acc-no. A program would be a better choice here. _________________ Kolusu - DFSORT Development Team (IBM)

ramy2016,
As mentioned earlier, it takes about 4 passes to get the desired results.
