Directory exclude from incremental and archive

Hi All,

I wanted to exclude the directory /PROD/APP/wrk_area from daily incremental and weekly archive. I gave the below statements in dsm.sys , but it only exclude the directory from incremental and not from archive. Can you please advise what I am missing here ....

DOMAIN /PROD
exclude.dir /PROD/APP/wrk_area
exclude.archive /PROD/APP/wrk_area


Thanks,
Frank
