Hi All,
I have a requirement to limit number of duplicate records in a file.

For e.g:
Below is the record pattern

Code:
AAA
AAA
BBB
BBB
BBB
BBB
CCC
CCC
CCC
DDD

Requirement is to have max 2 duplicate records. So my o/p should be

Code:
AAA
AAA
BBB
BBB
CCC
CCC
DDD

Thanks.

Assuming your data is in key order, extend record temporarily with a sequence number, with RESTART= for the key, and out OUTFIL with INCLLUDE=/OMIT= to do the limiting, with BUILD to drop off the extension.

The same could be achieved with WHEN=GROUP, but if the key is on each record, in the same position, then it is better to use the plain sequence number.

Thanks Bill & Pandora for your suggestion.

I used sequence number technique. It works. Thanks a lot
