We have a requirement to disable the dynamic triggers (HRMS Manager -> Other Definitions -> Dynamic Trigger Definition) prior to R12 upgrage. Is there any API available for this task? or any alternative way is there to disable these apart from manually disabling from front end.
Disabling a trigger is a DDL function, you're unlikely to find any APIs to do things like that. I guess it's a case of unchecking the 'Enabled' checkbox on each of the dynamic triggers you want to disable.
