output type not getting saved for the handling unit.

There is a output type "KEP6" which i am triggering manually for hanling unit. it is getting triggered properly and also there is no problem when i save it.

But when i go back and again open the same handling unit, the output type which i saved earlier do not appear. i tried triggering several time but same problem persists.

i just want to know all setttings, i have to check to make sure that the output type can be triggered manually. also let me know if there are some things, i have to check while triggereing the output type.
