Initialize apps from trigger

Hi All,

Ebs ver: 12.2.5

DB Ver: 12.1.0.2.0

I have a requirement to submit one concurent program from a trigger. For that I need to initialize the apps first before submitting the program. Please help me with any syntax to achieve this. I tried with following but it is not working. The concurrent prora is not submitting with the below methods.

1st method:

fnd_global.apps_initialize (user_id => x_user_id

                                          , resp_id => x_resp_id

                                          , resp_appl_id => x_resp_appl_id);

Then call the fnd_request.submit_request to submit the program.

2nd Method:

x_return_code := fnd_request.set_mode (TRUE);
