In oracle standard form when select the field lov when-validate-Item trigger is firing need to prevent that trigger.
please give me solution how to prevent When-validate-Item
What do you mean with "oracle standard form"? Are you working on the eBusiness-suite? If so, this might be a forms personalization-question which you have to ask in the appropiate forum.
Ok how about this:

if system.trigger_item <> 'MYFIELD' then
do the regular stuff
